It has since grown to cover all Wacom tablets, USB and serial, running on various different Linux distributions. As of December 2002, this project has transformed into the Linux Wacom Project. Work on this document is on-going so if you find an error, have a question, or have something to add, please send an email to: linuxwacom-discuss@lists.sf.net . 1.1 - Success Stories Originally, this document dealt only with Redhat 8.0. I will extend this to cover as many different distributions as possible, but I can personally only test on machines at my disposal. At present, that means Redhat 8.0, 9.0, and Mandrake 9.0. If you have success stories for a distribution or version not mentioned, let me know so I can update the document. * Redhat o Fedora core 2 final - tested on kernel 2.6.5-1.358 o Fedora core 2 test1 - tested on kernel 2.6.1-1 o Fedora core 1 - tested on kernel ??? o Redhat 9.0 - tested on kernel 2.6.2 o Redhat 9.0 - tested on kernel 2.6.0 o Redhat 9.0 - tested on kernel 2.4.24 o Redhat 9.0 - tested on kernel 2.4.22 o Redhat 9.0 - tested on kernel 2.4.20-6 o Redhat 8.0 - tested on kernel 2.4.18-24.8.0 o Redhat 8.0 - tested on kernel 2.4.18-19.8.0 o Redhat 8.0 - tested on kernel 2.4.18-18.8.0 o Redhat 8.0 - tested on kernel 2.4.18-17.8.0 o Redhat 7.3 - tested on kernel 2.4.18-17.7.x o Redhat 7.2 - tested on kernel 2.4.18-17.7.x o Redhat Enterprise Linux - tested on kernel 2.4.21-4 * Mandrake o Mandrake 9.1 o Mandrake 9.0 - tested on ??? o Mandrake 8.2 - tested on kernel 2.4.18-6mdk * Gentoo o Gentoo 2004.2, Xorg-X11 6.7.0, linux-2.6.8-rc3-mm2 o Gentoo 2004.1, Xorg-X11 6.7.0, kernel 2.4.25 o Gentoo 2004.1, Xorg-X11 6.7.0, kernel 2.6.5 o Gentoo 1.4rc, XFree86 4.2.0, kernel 2.4.19 o Gentoo 1.4, XFree86 4.3.0-r5, kernel 2.6.3 (*can not run wacomcpl and xsetwacom*) * Debian o Debian (sid) - XFree86 4.3 on 2.6.6 (see Building wacom.ko On Debian Sid (unstable) <#debwacom>) o Debian (sid) - XFree86 4.3(?) on 2.6.0 (*can not run wacomcpl and xsetwacom*) o Mepis 200310 (Debian unstable) - XFree86 4.3 on 2.4.22 o Debian Woody - XFree86 4.2 on 2.4.20 o Debian Stable 3.0 - XFree86 4.3 on 2.4.18 (*can not run wacomcpl and xsetwacom*) o Debian Stable - XFree86 4.1 (see Building wacom_drv.o On Debian Stable <#debwcmdrv>) * Slackware o Slackware 9.0 o Slackware 8.1, (standard release) * SuSE o Suse Linux 8.0, kernel 2.4.18, XFree 4.2 o Suse Linux 9.1, kernel 2.6.4, XFree 4.3.99 (4.4.0 RC 2) o Suse Linux 9.1, kernel 2.6.5, XFree 4.3.99 (4.4.0 RC 2) * FreeBSD o version 4.10, serial only * Source Mage o gcc 3.2.2, Linux 2.4.21-pre4-ac3, XFree86 4.2.1 and 4.3.0 * PowerMac o Yellow Dog Linux 3.0.1 [Redhat variant for PPC] (see Building wacom driver On PowerMac <#ppcwcmdrv>) 1.2 - How To Use This Document In terms of document organization, if you have not figured it out already, you can browse the document one page at a time, or you can click on the ALL link and view the entire thing in one long page. Where the guide differs between distributions or packages, I have added a comment which appears indented with a light blue background. Also, it bears mentioning since it's a detail often missed: there are two drivers in the Linux Wacom Project- wacom.o and wacom_drv.o. The first driver is the USB kernel driver. The second driver is the XFree86 Wacom driver. Serial users need only be concerned with the wacom_drv.o driver. USB users need both. If you try to use the wacom_drv.o driver in place of the wacom.o kernel driver or visa-versa, things generally won't work. Next, this document was written with the assumption that you are starting from scratch with a relatively recent distribution of the Linux kernel. Also, if you have already added lines to your XFree86 configuration file (XF86Config or XF86Config-4), you should comment them out and restart X. Since we'll be stepping through the entire process, we need X to ignore the tablet until we're ready. Otherwise, X will just get in the way. Finally, if you know what you're doing, you can leave your X settings intact, print this out, switch to runlevel 3, and follow along from the console. The newer packages should have an HTML version of this document in the docs directory. And of course, there's always lynx for the gurus out there, which is why this document is written out in plain vanilla HTML. 1.3 - Resources and References The Linux Wacom Project This site hosts the current version of this document as well as drivers, development tools, and mailing lists.

They are also sold as embedded products in certain tablet PC's. I will cover all three types, but the serial case is the most straightforward, so we'll start there. *Serial Tablet Operation - The Short Story* When a Wacom serial tablet is connected to a COM port, software can interact with it directly by opening the appropriate device, usually /dev/ttyS0. The XFree86 Wacom driver (wacom_drv.o) does precisely this, and all stylus movements are converted into XInput events for programs like the Gimp to turn into fluid brush strokes. Wacom tablets are capable of handling a number of different data protocols, and the Linux Wacom Project code currently utilitizes two, Wacom Protocol IV and Protocol V. Each operates with a fixed-sized packet, the length of which depends on the model and ROM version. When the serial tablet is reset, it defaults to a standard baud rate, often 9600 baud. From there, the device type can be queried, and if the tablet supports it, the baud rate increased to a higher value. Additionally, model parameters like tablet size can be queried directly to determine which features are available. Once configured, the tablet streams data back to the application as tools are brought into and out of proximity, are pressed against the tablet surface, or are tilted or inverted. *USB Tablet Operation - The Long Story* Initially at least, the USB Wacom tablet is an HID compliant device, and when first connected to the computer, will identify itself as such. Unfortunately, this is not what you want because in this mode, you will not get any of the fancy features. The hid-core.c, mousedev.c, and usbmouse.c kernel drivers contain exceptions for the wacom; when the device is detected, they ignore the tablet. In this way, the more sophisticated wacom driver has the opportunity to assume control. The first thing that the driver does is register itself with the USB subsystem and wait for work to do. When the user plugs the device in, or the device is first detected, the USB subsystem shops the vendor and device identifier around, checking it against different drivers. The wacom driver takes responsibility for the tablet and then notifies the event system that it will be providing data. It then asks the tablet to switch from HID-compliant mode to "mode 2", a wacom-specific protocol which allows for values like pressure, Z rotation, and tilt. As information arrives, the wacom driver dutifully converts the data into real-world values and hands it on to the event system. From here, any usermode application can get access to the event data by opening /dev/input/event0. A stream of events including mouse movements, clicks, and proximity updates can be read from the device. Similar to the serial case, XFree86's Wacom driver (wacom_drv.o) has the ability to read this device, and performs filtering on the data before convert the Linux input events into XInput events. By breaking the responsibility for the data into three distinct levels, the kernel code remains simple and robust, the applications generalized, and the fancy features commonly accessible to all GUI applications in the X window system itself. This document walks down the entire data path from the USB kernel driver to the gimp application. *Embedded Device Operation - Tablet PC with Wacom Digitizer* The Wacom digitizers embedded in Tablet PCs utilitizes a special protocol IV, ISDV4. Similar to the conventional serial tablets, tablet PCs use a serial controller (UART). But, normally, they are not set to any serial ports. They are effectively serial devices, but require special configuration (setserial) under Linux. 2.0 - Getting It Together This section is devoted to preparing your system for the installation. Every distribution handles kernel modules and file locations a bit differently, so the goal here is to return everything to a known state. In some cases, your distribution may have automatically loaded certain modules which you will now need to unload. USB users will need to pay specific attention to discussions related to kernel drivers and modules. Serial tablet users have it much easier, and can bypass this. Both users will need to make changes to the XFree86 configuration file. Incidentally, some distributions detect new hardware on boot. If you allow Redhat's "anaconda" for instance to automatically configure (or remove) your USB tablet, it may undo some of the settings you will make here. Until Redhat's installation program recognizes Wacom tablets as non-HID devices by default, you are best off in my opinion to /not/ allow it to configure the device. Just a warning. 2.1 - Before We Start From the beginning, let's make certain that we are on the same page. First, unplug your serial or USB Wacom. If you have Wacom related lines in your XF86Config or XF86Config-4 files already, you should comment them out or remove them. In particular, this includes InputDevice sections with a driver set to "wacom" and their corresponding InputDevice lines in ServerLayout. When that's done, restart X. It would be a wise idea at this time to check your XFree log file for references to wacom, wcm, or tablet. If X persists in trying to interact with the tablet, things will only be problematic later. The log file is often found at /var/log/XFree86.0.log. The remaining instructions deal with unloading old USB driver modules from the kernel. Serial users can skip forward to the Downloading the Code <#download> page. USB users should unload the old modules. [jej@ayukawa jej]$ su - [root@ayukawa root]# lsmod | grep wacom *wacom* 8020 0 (unused) input 5920 0 [*evdev* *wacom* mousedev keybdev hid] usbcore 77024 1 [*wacom* usb-storage snd printer hid usb-uhci] [root@ayukawa root]# rmmod wacom evdev The kernel now knows nothing about the Wacom or how to handle event-based input devices. If you get an error unloading (busy driver perhaps), try rebooting. Check the presence of the input devices in the /dev/input directory. You should find approximately 114 devices with names such as event*, mouse*, keyboard, js*, and ttyACM*. On some distributions, Mandrake 9.0 for instance, the /dev directory is managed by devfs; Redhat 8.0 does not use it. When devfs is running, the /dev/input directory may be present, but its contents may be missing if the evdev driver is not loaded. This is perfectly fine. If you are not using devfs and the /dev/input directory or mouse0/event0 devices are not present, your distribution may be lacking these devices. This could be an oversight, or it could be an indication that your distribution is too old. I believe you can verify whether devfs is running by executing /mount/ and looking for "none on /dev type devfs (rw)" or similar. We are interested in two devices, mouse0 and event0. [root@ayukawa root]# cd /dev/input [root@ayukawa input]# ls -la mouse0 event0 crw------- 1 root root 13, 64 Aug 30 16:31 event0 crw------- 1 root root 13, 32 Aug 30 16:31 mouse0 [root@ayukawa input]# xxd mouse0 xxd: mouse0: No such device [root@ayukawa input]# xxd event0 xxd: event0: No such device If after executing /xxd mouse0/ you *did not* receive the "xxd: mouse0: No such device" message, then the input device is still loaded; go back and try running /rmmod evdev/ again. Once the new drivers are compiled and installed, this command will stream information from the Wacom tablet. mouse0 behaves like a PS/2 style mouse. event0 provides extensive information about the tablet including position, tilt, pressure, and buttons. It can also track at least two different tools simultaneously (Intuos and Intuos2). 2.2 - Downloading the Code The file linuxwacom-0.6.4.tar.bz2 is the stable package and contains files that you will need to get your serial or USB tablet working. The current beta package linuxwacom-0.6.5.tar.bz2 is also available and may be used by people who are willing to risk an occasional kernel panic to help test new features. I will never put a beta package on this site that I am not running myself on my primary development machine, so you can be certain that if there are any obvious show stoppers, they will be fixed before you get to see them. Unpacking the tarball is usually a one-step process, but I show both steps in case the typical -jxf option doesn't work with tar. [jej@ayukawa jej]$ bunzip2 linuxwacom-0.6.4.tar.bz2 [jej@ayukawa jej]$ tar -xf linuxwacom-0.6.4.tar [jej@ayukawa jej]$ cd linuxwacom-0.6.4 Once in the package directory, you need only to configure and build the code. This is described in more detail as you continue. The executables and wacom_drv.o are installed automatically; the kernel drivers have different installation procedures depend on the kernel source you use. If you are interested, the following tables contain the package contents and release dates. Otherwise, let's continue.

You can run the configure script now as the samples below demonstrate, or later when you reach the section of the document that explains what specifically needs to be configured and why. This page is provided largely as a reference. Versions of linuxwacom-0.2.1 and greater are based on GNU's configure script based build environment. By default, xidump, wacdump, xsetwacom, and wacomcpl are built. Additional options include replacement kernel drivers for hid, mousedev, evdev, and usbmouse as well as building the XFree86 driver from scratch. Lastly, remember that for every --enable option, there is also an equivalent --disable option. Building Kernel Modules - USB Only In order to build kernel modules, you will need the kernel source installed on your system. If you are running on Redhat or Mandrake, you can get it by installing the kernel-source RPM. The kernel source directory is assumed to be either /usr/src/linux-2.4 or /usr/src/linux. If your kernel sources are elsewhere, you will need to specify the directory with the --with-kernel option described below. For kernel 2.6, you need to configure the kernel modules (wacom, hid, mousedev, usbmouse, evdev) under your kernel source directory before configuring linuxwacom. Module Versioning - USB Only The script attempts to discover if the kernel is using module versioning by detecting the presence of version numbers in the hid.o module of the currently active kernel. Recent package versions also check for hid.o.gz which exist on Mandrake systems. The configure script may not be able to d etermine if kernel module versioning should be enabled or not, in which case it will say "unknown, assuming no." If module versioning is disabled when it should be enabled, depmod will complain about missing symbols but otherwise, things will probably work fine. If it is enabled when it should be disabled, the code may not compile, and it almost certainly will not load properly. If the configure script fails to determine the correct value, the default action of disabling module versioning is the better choice, and you can allows enable it manually and rebuild if depmod complains. The XFree86 XInput Driver - USB and Serial Generally, you will not need to build wacom_drv.o since it ships in binary form in the prebuilt directory. There are 4 prebuilt binaries for XFree86 4.2 and 4.3 corresponding to kernel 2.4 and 2.6, respectively. If no one works for you, building from source may be your only option. See the Building wacom_drv.o From Scratch <#builddrv> page for more information. Library Dependencies - ncurses and XLib Various utilities in the linuxwacom package require not only specific libraries, but their development header files as well. The ncurses package is one such example. Most distributions install the ncurses libraries by default, but the header files are often located in a separate package. You will need both. On Redhat 8.0, they can be found in the ncurses-devel RPM. Similarly, if you wish to test your tablet using xidump to view XFree86 input events, you will need the XFree86 development headers. On Redhat, they are contained in the XFree86-devel package. If any packages are missing, the configuration will warn you and disable building any programs that depend on them. Processor Type The processor type is determined by the script and used to build the kernel modules. If it guesses incorrectly, or you would prefer a different setting, use the --with-arch option described below. Linux Specific Features The Linux wacom driver uses the Linux input subsystem, as does the USB portions of the XFree86 driver. Consequently, if you are building on a non-Linux system, the USB code will not work for you. This is detected, and a comment to that effect is added to the configuration summary. I recognize that FreeBSD and similar systems have USB support; however, until someone can bridge the gap between the FreeBSD kernel and the XFree86 driver, the problem is largely unsolved. Contributions are of course welcome. The Linux-specific features can be enabled/disabled using the --with-linux argument. Configuration Options The following options are provided as reference. You will probably not need to use any of these options, but more obscure systems may need all of them. Each section of the document identifies which options are necessary and when. Option Default Builds --enable-wacom *no* wacom.o kernel driver --enable-wacdump *yes* wacdump LinuxInput event monitor --enable-xidump *yes* xidump XInput event monitor --enable-libwacomcfg *yes* libwacomcfg Dynamic library for xsetwacom --enable-libwacomxi *yes* libwacomxi Dynamic library for wacomcpl --enable-xsetwacom *yes* xsetwacom XFree86 wacom driver configuration comannd --enable-hid no hid.o replacement kernel driver (not normally necessary) --enable-usbmouse no usbmouse.o replacement kernel driver (not normally necessary) --enable-evdev no evdev.o replacement kernel driver (not normally necessary) --enable-mousedev no mousedev.o replacement kernel driver (not normally necessary) --enable-wacomdrv yes wacom_drv.o XFree86 driver (binary is available in prebuilt directory) --enable-modver=yes|no best guess enables kernel module versioning; usually guesses correctly, but can be enabled or disabled if not --with-kernel=dir best guess Specifies the kernel source directory if configure cannot guess correctl. --with-xf86=dir none Specifies the XFree86 build directory --with-tcl=dir /usr Specifies the tcl directory. The tcl's include and lib directories should be under this directory. If tcl.h is not in dir/include, it will be searched under dir directly --with-tk=dir /usr Specifies the tk directory. If tk is under the same directory as tcl, this option can be eliminated. Otherwise, the tk's include and lib directories should be under this directory. If tk.h is not in dir/include, it will be searched under dir directly --with-arch=arch best guess Specifies the architecture if configure guesses incorrectly --with-linux=yes|no best guess Specifies if compiled on a Linux system; USB code is Linux specific --with-xlib=yes|no best guess Specifies if building xlib-based programs; xidump uses XInput headers Configuration Samples Here is a sample output of the script on a Redhat 8.0 system: [jej@ayukawa linuxwacom]$ ./configure checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes ... checking for processor type... *i686* checking for kernel module versioning... *yes* checking for kernel sources... */usr/src/linux* checking for XLib include directory... *found* checking for XLib header files... *found* ... checking for ncurses.h... *yes* ... ---------------------------------------- BUILD ENVIRONMENT: architecture - i686 linux kernel - yes 2.4 module versioning - yes kernel source - yes /usr/src/linux XFree86 - no XLib - yes TCL - yes /usr TK - yes /usr ncurses - yes GTK - 2.0.6 BUILD OPTIONS: wacom.o - no wacdump - yes xidump - yes libwacomcfg - yes libwacomxi - yes xsetwacom - yes hid.o - no usbmouse.o - no evdev.o - no mousedev.o - no input.o - no tabletdev.o - no wacom_drv.o - no ---------------------------------------- The configure script is pretty simple, so if you find any problems and are inclined to fix them, please send me your patch so I can include the change in future releases. The following sample command-line will build everything but wacdump while disabling module versioning. It also has a user-specified kernel source directory: [jej@ayukawa linuxwacom]$ ./configure --enable-hid --enable-usbmouse \ --enable-evdev --enable-moudedev --enable-input --enable-wacom \ --with-xf86=/usr/src/redhat/BUILD/XFree86-4.2.0 \ --with-kernel=/home/jej/src/linux --with-tcl=/usr/local/ActiveTcl \ --disable-modver --disable-wacdump checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes ... checking for processor type... i686 checking for kernel module versioning... *yes* checking for kernel sources... /usr/src/linux-2.4 checking for valid XFree86 build environment... *ok* ... ---------------------------------------- BUILD ENVIRONMENT: architecture - i686 linux kernel - yes 2.4 module versioning - *no* kernel source - *yes /home/jej/src/linux* XFree86 - *yes /usr/src/redhat/BUILD/XFree86-4.2.0* XLib - yes TCL - *yes /usr/local/ActiveTcl* TK - *yes /usr/local/ActiveTcl* ncurses - yes GTK - 2.0.6 BUILD OPTIONS: wacom.o - *yes* wacdump - *no* xidump - yes libwacomcfg - yes libwacomxi - yes xsetwacom - yes hid.o - *yes* usbmouse.o - *yes* evdev.o - *yes* mousedev.o - *yes* input.o - *yes* tabletdev.o - no wacom_drv.o - *yes* ---------------------------------------- Notice that the configure script guessed module versioning was enabled by default, but was disabled by the command-line option --disable-modver. Similarly, the wacdump program which is enabled by default was also disabled. All the kernel modules and the XFree86 wacom driver are enabled. If the configure script fails to find something that it is looking for, it may disable some options that you previously enabled on the command-line. If this happens, check the output for a warning like the following: *** *** WARNING: *** Unable to compile wacom_drv.o without XF86 build environment *** wacom_drv.o will not be built *** In this particular case, the XFree86 driver was enabled, but the --with-xf86 option was not specified. Without the build environment, the module cannot be compiled and was consequently disabled. 2.4 - The Root Account If you are comfortable with the root account, paths, the /sbin directory, and programs like /modprobe/, you can skip this section. This is largely to clarify some things for people who are new to Linux and get tripped up with the root account and paths. This is not meant to be a tutorial, so if this is over your head, I would recommend reading a book on Linux command line usage. All examples in this document assume the bash shell. Many of the procedures in this document need root access, and the commands that are executed are located in places on the system that are not normally accessed by typical users. In order to run the /modprobe/ command, for instance, you must have root access. Additionally, if the /sbin directory which contains /modprobe/ does not appear in your path, you must specify the full pathname, /sbin/modprobe, to run the command. Here is an example of the problem, followed by solutions. [jej@ayukawa jej]$ modprobe foo bash: modprobe: command not found [jej@ayukawa jej]$ locate modprobe /sbin/modprobe [jej@ayukawa jej]$ echo $PATH /bin:/usr/bin: ... :/home/jej/bin Normal users do not have /sbin in their path, so running /modprobe/ directly fails. Running the program using the full pathname (/sbin/modprobe) will solve this, as will adding /sbin to the path. But there is another problem, as we will see: [jej@ayukawa jej]$ /sbin/modprobe foo foo.o: create_module: Operation not permitted Normal users are not allowed to run this command. For that, we need to be root. The /su/ command stands for "substitute user" since it can be used to become /any/ user on the system, but it is generally known by the incorrect but very memorable mnemonic "superuser." [jej@ayukawa jej]$ su Password: [*root*@ayukawa jej]# whoami root Note the change to the root account, and the additional change from $ to # on the prompt. I maintain this convention in all the examples in this document, so if you get an "access denied" error, check the prompt. You probably need to be root. Now that we have root access, is /sbin in our path? No. We have only been granted the privileges of root; we are not really in the root account's environment. Most notably, the home directory ($HOME) changes, but the path ($PATH) stays the same. Thus, becoming root is not sufficient to run /modprobe/ without the full pathname, but does solve the access problem. [root@ayukawa jej]# modprobe foo bash: modprobe: command not found [root@ayukawa jej]# export PATH=$PATH:/sbin [root@ayukawa jej]# modprobe foo [root@ayukawa jej]# In this example, the user adds the /sbin directory to the path and can run /modprobe/ normally. /export/ is a bash shell command that changes aspects of your environment; in this case, /sbin is appended to the path. In the highly unlikely event that you are using a different shell, which for novice users seems unwise to me, you would need to use a different command. Redhat, Mandrake, and similar distributions all use bash by default, so it is unlikely that you would be using anything else. At any rate, changing the path is a reasonably good solution, if you can remember the syntax of the /export/ command. Another approach to this problem is to do more than just "be root," but to run in the root account's environment. This is accomplished with the "su -" command and provides you with root's normal path, including the /sbin directory. The unfortunate side-effect is that you wind up in root's home directory, requiring you to /cd/ back to the original directory in which you were working. [jej@ayukawa src]$ pwd /home/jej/src/linuxwacom/src [jej@ayukawa src]$ su - [root@ayukawa root]# cd /home/jej/src/linuxwacom/src [root@ayukawa src]# echo $PATH /bin:*/sbin*:/usr/bin: ... :/root/bin Here, the user starts in the package's src directory, but upon invoking "su -" is magically shuttled off to root's home directory. A quick /cd/ back to the package directory and all is better. And, as demonstrated above, the path conveniently contains /sbin. So that leaves you with two immediate options, and one potential long-term option: Option One: Become root and add /sbin to the path. [jej@ayukawa src]$ su [jej@ayukawa src]# export PATH=$PATH:/sbin Option Two: Become root using root's environment and /cd/ back. [jej@ayukawa src]$ su - [root@ayukawa root]# cd /home/jej/src/linuxwacom/src Option Three (recommended): Add /sbin to your personal account's path [jej@ayukawa src]$ export PATH=$PATH:/sbin [jej@ayukawa src]$ su [root@ayukawa src]# echo $PATH /bin:/usr/bin: ... :/home/jej/bin:*/sbin* By adding the path early in the session, it becomes available every time you /su/ to root later on. You could also add the /export/ command to the .bash_profile file in your home directory and have the path set automatically when you log in. To exit from the root account and return to your normal account, you can use the /exit/ command or type Ctrl-D on an empty line. [root@ayukawa src]# exit [jej@ayukawa src]$ If any of this is not explained clearly, drop me a line and let me know where you got stuck. I'd be happy to clarify directly and update this page for future readers. 3.0 - The USB Kernel Driver Serial tablet users rejoice: you can skip this entire section. Please go to the Using wacdump <#wacdump> page for details on viewing the tablet output. USB users stay put; we need to tweak your kernel. Kernel modules must be recompiled for each new kernel so I can't just provide binaries. By the time you read this, my present kernel will be entirely out of date with yours. In any event, many new features are available in the latest drivers from the Linux Wacom Project, so I wholly recommend using them over the drivers provided by your standard distribution. Rest assured, efforts are being made to get these changes merged back into the Linux kernel. 3.1 - Updated wacom.c The wacom.c driver that is available in linuxwacom-0.6.4.tar.bz2 has a number of updates which cannot be found in many distributions yet. This driver supports the three new tablets: CintiqPartner, Graphire3, and Volito. The driver also contains additional debugging code which may be useful in diagnosing data flow problems. Steve Wallace has submitted a howto for compiling the related kernel pieces on Debian Sid (Unstable) which is running XFree86 4.3 and kernel 2.6.6 as of this writing. It can be viewed at page Building wacom.ko On Debian Sid (unstable) <#debwacom>. 3.2 - Building wacom.c (for kernel 2.4) To build the wacom.o kernel module, you need configure the package with --enable-wacom option. The kernel sources are required as described on the configuration <#config> page. Here's how the configuration should generally look: [jej@ayukawa linuxwacom]$ ./configure --enable-wacom ... checking for valid kernel source tree... *ok* ... ---------------------------------------- BUILD ENVIRONMENT: architecture - i686 linux kernel - *yes 2.4* module versioning - yes kernel - *yes /usr/src/linux* XFree86 - no XLib - yes /usr/X11R6 TCL - yes /usr TK - yes /usr ncurses - yes GTK - 2.0.6 BUILD OPTIONS: wacom.o - *yes* wacdump - yes xidump - yes libwacomcfg - yes libwacomxi - yes xsetwacom - yes hid.o - no usbmouse.o - no evdev.o - no mousedev.o - no input.o - no tabletdev.o - no wacom_drv.o - no ---------------------------------------- As shown above, the kernel directory was detected and the wacom.o module will be built. If the kernel option shows "no", you will need to specify the --with-kernel option and the correct directory. To build the driver, just run /make/. The output will be a file called wacom.o. It is located in the linuxwacom package's src/2.4 directory for versions older than 2.4.22. For versions 2.4.22 or newer, it is in src/2.4.22 directory. This is your replacement driver. 3.3 - Building wacom.c (for kernel 2.6) To build the wacom.o kernel module, you need to configure wacom as a kernel module under your kernel source tree first. The kernel sources are required as described on the configuration <#config> page. Then, you need to configure the package with --enable-wacom option. Here's how the configuration should generally look: [jej@ayukawa linuxwacom]$ ./configure --enable-wacom ... checking for valid kernel source tree... *ok* ... ---------------------------------------- BUILD ENVIRONMENT: architecture - i686 linux kernel - *yes 2.6.2* module versioning - yes kernel - *yes /usr/src/linux* XFree86 - no XLib - yes /usr/X11R6 TCL - yes /usr TK - yes /usr ncurses - yes GTK - 2.0.6 BUILD OPTIONS: wacom.o - *yes* wacdump - yes xidump - yes libwacomcfg - yes libwacomxi - yes xsetwacom - yes hid.o - no usbmouse.o - no evdev.o - no mousedev.o - no input.o - no tabletdev.o - no wacom_drv.o - no ---------------------------------------- As shown above, the kernel directory was detected and the wacom.o module will be built. If the kernel option shows "no", you will need to specify the --with-kernel option and the correct directory. To build the driver, just run /make/. The original wacom.c at your kernel source tree is backed up as wacom.c.2.6. The wacom.c at linuxwacom package's src/2.6.x is copied to your kernel source tree. All the building process is done in your kernel source tree. If everything works properly, you'll see the following from the make: [jej@ayukawa linuxwacom]$ make ... Making all in 2.6.2 make[3]: Entering directory `/home/jej/linuxwacom/src/2.6.2' if test ! -f /home/jej/linuxwacom/src/2.6.2/wacom.o; then \ cd /usr/src/linux; make; cd /home/jej/linuxwacom/src/2.6.2; \ cp -f /usr/src/linux/drivers/usb/input/wacom.o .; \ fi make[4]: Entering directory `/usr/src/linux' make[5]: `arch/i386/kernel/asm-offsets.s' is up to date. CHK include/linux/compile.h *CC [M] drivers/usb/input/wacom.o* Kernel: arch/i386/boot/bzImage is ready Building modules, stage 2. MODPOST *LD [M] drivers/usb/input/wacom.ko* make[4]: Leaving directory `/usr/src/linux' make[3]: Leaving directory `/home/jej/linuxwacom/src/2.6.2' ... The output will be a file called wacom.ko. In the above case, it is located at /usr/src/linux/drivers/usb/input. 3.4 - Testing If wacom.o Will Load (for kernel 2.4 only) Before we install the wacom driver, we need to test that it will load properly. We do this by loading the driver manually. We will also need to be root <#root> to do this. WARNING: there is a small chance that this will bomb your kernel, so we run /sync/ to write all the stale buffers to the disk. People using ext3 have little to worry about, but it's always good to be prepared for the worst. At the very least, save your work. [root@ayukawa linuxwacom]# sync From the package's src directory, we unload any previous modules and load the new one. [root@ayukawa linuxwacom]# cd src [root@ayukawa src]# rmmod wacom [root@ayukawa src]# insmod ./wacom.o # for those about to rock, we salute you. Well, if you did not bomb, then good. And if you did, well, sorry. So far, we have not had any reports of this happening, so please send in yours. Incidentally, if you run "insmod wacom.o" and happen to be in the wrong directory, the old driver reloads, sometimes without warning. I therefore changed this to read "insmod ./wacom.o" which seems to prevent this from happening. To be certain, you can check the log file for the correct version number. [root@ayukawa src]# tail /var/log/messages Nov 08 20:34:41 ayukawa kernel: usb.c: registered new driver wacom Nov 08 20:34:41 ayukawa kernel: Reporting max 30480, 31680 Nov 08 20:34:41 ayukawa kernel: wacom.c: Setting tablet report for tablet data Nov 08 20:34:41 ayukawa kernel: input0: Wacom Intuos2 12x12 on usb2:3.0 Nov 08 20:34:41 ayukawa kernel: wacom.c: *$1.40-j0.6.3* Vojtech Pavlik Nov 08 20:34:41 ayukawa kernel: wacom.c: USB Wacom Graphire and Wacom Intuos tablet driver (*MODIFIED-DEBUG*) The important detail is the version number. A version number like "1.30" is an original kernel version and not from the linuxwacom package. The correct version should also have the -j0.6.3 portion as well. Also, future versions of the driver will say "LINUXWACOM-DEBUG" or similar rather than "MODIFIED-DEBUG" as shown above. This is to help differentiate between the stock kernel driver and those available from the Linux Wacom Project. If you get errors inserting the module, then you may need to reconfigure and build with module versioning disabled. If it loads without a hitch, move on to the next part. 3.5 - Installing wacom.o *For Kernel 2.4.x:* To install or not to install, that is the question. Since the driver is in memory, you can pretty much use it this way throughout the rest of this document. Anywhere you see "modprobe wacom", you'll instead need to "insmod ./wacom.o". You'll also need to be careful that you are in the package's src directory. If you instead use the less-specific command "insmod wacom.o" from a directory other than the package's src directory, /insmod/ will load the driver from the kernel modules directory instead. The result is that you'll be using the wrong driver. Why would you not install the driver? Well, for one, you may be using a beta driver, and if the system crashes (you get an Oops or things come unglued in other ways), it would be nice to reboot and have the original drivers load instead. When should I install the driver? When you're comfortable that the driver will not crash your system. The linuxwacom tarballs will be marked as beta if I am not absolutely convinced that they are stable. On the other hand, the new features will be in beta tarballs before they are marked stable, so there you have it. For the first time through this document, I would recommend installing the files found in the stable tarball. If you really know what you're doing, just load the drivers manually like in the previous section Testing If wacom.o Will Load (for kernel 2.4 only) <#testwacom>. On some distributions, Mandrake included, the wacom.o driver that appears in the kernel modules directory appears to be compressed. If you cannot find wacom.o using the method below, try locating wacom.o.gz instead. People who encountered this problem were able to run gzip on the module and copy that instead. Installing the driver requires knowing where it belongs. A little research will help here. By using the /locate/ command, you can find all copies of the original driver on the computer. jej@ayukawa wacom]$ locate wacom.o /lib/modules/2.4.18-14/kernel/drivers/usb/*wacom.o* /lib/modules/2.4.18-18.8.0/kernel/drivers/usb/*wacom.o* [jej@ayukawa wacom]$ uname -r *2.4.18-18.8.0* On this computer, there are two kernels installed. /uname/ identifies the currently active kernel as 2.4.18-18.8.0. The correct driver to replace is therefore at /lib/modules/2.4.18-18.8.0/kernel/drivers/usb/wacom.o. You will need to be root to replace this file, and it is a very good idea to make a backup copy. [jej@ayukawa wacom]$ su - [jej@ayukawa root]# cd /lib/modules/2.4.18-18.8.0/kernel/drivers/usb [jej@ayukawa usb]# cp *wacom.o* /home/jej/src/wacom/*wacom_old.o* [jej@ayukawa usb]# cp /home/jej/src/wacom/*wacom.o* *wacom.o* Here, I've saved the original to wacom_old.o and copied my new driver over it. You should substitute directory names as appropriate. *NOTE: Don't leave the backup copy in the same directory as the original.* /depmod/ will treat both as valid drivers, regardless of their names. Copy the original somewhere outside of the kernel module directory to ensure that this does not happen. In at least one case, the backup driver was loaded instead of the new one due to a curious dependency issue. Finally, it is always a good thing to update the module dependencies. This is where you find out if the module was compiled without kernel module versioning. The following command, even if it generates errors is relatively benign. If it fails, then there is no harm done. It just means that you will have to load modules in the correct order since the system will not be able to guess for you. [jej@ayukawa usb]# depmod -e If you get no errors and no output, everything is fine, and the module was compiled, linked, and installed properly. If you received unresolved symbols like usb_set_idle or printk, then you need to reconfigure with module versioning enabled and recompile. Or not. As I said, it is not critical. *For Kernel 2.6.x:* [jej@ayukawa wacom]$su [jej@ayukawa wacom]#cd your-kernel-src-dir [jej@ayukawa linux]#make install [jej@ayukawa linux]#make modules_install [jej@ayukawa linux]#reboot The original wacom.c from your kernel source was backed up at your-kernel-src-dir/drivers/usb/input/wacom.c.2.6. If there is anything wrong with the new wacom driver, do the following: [jej@ayukawa wacom]$cd your-kernel-src-dir [jej@ayukawa linux]$cp drivers/usb/input/wacom.c.2.6 drivers/usb/input/wacom.c [jej@ayukawa linux]$make [jej@ayukawa linux]#su [jej@ayukawa linux]#make install [jej@ayukawa linux]#make modules_install [jej@ayukawa linux]#reboot Then post a message to the group so someone can help you out. 3.6 - Loading the wacom Driver (for kernel 2.4 only) If you have installed the driver, now is the time to test whether it will load when needed. If you have not installed it, but are instead using insmod, substitute /insmod mydir/src/wacom.o/ where you see /modprobe wacom/ below. It is important that you use the correct wacom.o file, the one you just built, since insmod may load the old driver if it cannot find the one you have specified. I am assuming that you are using a USB device, so you will also need to modprobe for either usb-uhci or usb-ohci depending on your hardware. Try them both! The wrong module will cough up an error for you. The important features of the stylus are available through the Linux event drivers, so load those too. With some clever additions to /etc/modules.conf, you can probably have these automatically loading for you whenever the tablet is activated. So far, I haven't figured out how to make this work reliably, so I've added the commands to my /etc/rc.d/rc.local file. On Redhat 7.2 and possibly on other older distributions, mousedev and input are not loaded by default. Without them, the wacom driver may fail to load, due to unresolved symbols, and the mouse driver may not receive wacom mouse events, even if loaded afterwards. [jej@ayukawa usb]# rmmod wacom [jej@ayukawa usb]# modprobe usb-uhci (or usb-ohci) [jej@ayukawa usb]# modprobe input [jej@ayukawa usb]# modprobe mousedev [jej@ayukawa usb]# modprobe wacom (or insmod mydir/src/wacom.o) [jej@ayukawa usb]# modprobe evdev Check the system log for status messages pertaining to the wacom. Here's a copy of the messages from my version of the driver. [jej@ayukawa usb]# grep -i wacom /var/log/messages | tail Nov 08 21:23:35 ayukawa kernel: usb.c: registered new driver wacom Nov 08 21:23:35 ayukawa kernel: wacom.c: *v1.40-j0.6.3* Vojtech Pavlik Nov 08 21:23:35 ayukawa kernel: wacom.c: USB Wacom Graphire and Wacom Intuos tablet driver (MODIFIED) The original driver was version 1.30. This version number is 1.40-j0.6.3 so the correct driver was loaded. 3.7 - Testing Tablet Detection In this section we will plug the tablet into the computer and determine which driver, if any, claims control over the tablet. There are at least three drivers that are interested: 1) hid.o which may think it is an HID device, 2) usbmouse.o which may think it is an HID mouse, and 3) the wacom driver which should identify the tablet as its own. Any number of problems may be experienced here, so be prepared to spend some time looking at the logs. A good way to do this, if you are running X, is to open a separate xterm, su to root, and run /tail -f /var/log/messages/. The console window will stream anything that is appended to the log. 3.7.1 - Plug It In Test the tablet detection by plugging the wacom into the USB port and checking /var/log/messages again. You should see a flurry of activity. The exact output depends a lot on your particular kernel and distribution. This is Redhat 8.0 (2.4.18-17.8.0): [jej@ayukawa usb]# tail /var/log/messages Nov 08 21:26:11 ayukawa kernel: hub.c: USB new device connect on bus2/2, assigned device number 2 Nov 08 21:26:11 ayukawa kernel: *input0: Wacom Intuos2 12x12* on usb2:2.0 Nov 08 21:26:14 ayukawa /etc/hotplug/usb.agent: Setup wacom hid for USB product 56a/44/115 Nov 08 21:26:14 ayukawa /etc/hotplug/usb.agent: Setup *mousedev* for USB product 56a/44/115 And here it is again on Redhat 7.2 (2.4.18-17.7.x): [jej@sasami root]# tail /var/log/messages Nov 08 21:28:38 sasami kernel: hub.c: USB new device connect on bus1/1, assigned device number 2 Nov 08 21:28:38 sasami kernel: *input0: Wacom Intuos2 12x12* on usb1:2.0 Nov 08 21:28:39 sasami kernel: usb.c: registered new driver hiddev Nov 08 21:28:39 sasami kernel: usb.c: registered new driver hid Nov 08 21:28:39 sasami kernel: hid-core.c: v1.8.1 Andreas Gal, Vojtech Pavlik Nov 08 21:28:39 sasami kernel: hid-core.c: USB HID support drivers Nov 08 21:28:39 sasami kernel: mice: *PS/2 mouse* device common for all mice If all went well like above, the USB device was successfully detected and handled by the wacom driver; secondly, it was assigned input0. This presumably means that information like pressure and tilt will be received on /dev/input/event0. Lastly, the tablet was setup with mousedev or the generic PS/2 USB mouse driver, so that information should appear on /dev/input/mouse0. If instead you got any of the following lines in your log, the wacom driver /did not get control/. Either hid or usbmouse did. *input0,hiddev0: USB HID v1.00 Mouse* [Tablet XD-0608-U] on usb1:5.0 *input0: Tablet XD-1212-U* on usb2:2.0 The next section describes what to do if the wacom driver did not get control. Otherwise, skip on to Viewing the Raw Data <#viewdata>. 3.7.2 - Wacom Driver Does Not Get Control If the wacom driver did not get control, and instead you see "Tablet XD-1212-U" or similar in its place, then this section is for you. Otherwise, consider yourself lucky and skip on to the next section, Viewing the Raw Data <#viewdata>. For the unlucky, there is a good possibility that your kernel is slightly out of date and that your mousedev.c, hid-core.c, usbmouse.c and evdev.c files need some help. When the Tablet XD-1212-U driver comes up, either mousedev.o or co has discovered your tablet, decided it was an HID device, and grabbed it. Or your hid.o did not add that tablet as a supported device. This is bad news because HID tablets only output relative coordinates and nothing about pressure. You are in good company though because a number of people have reported this, even on some fairly up-to-date distributions. You will learn how to fix it in next section. The modules included in linuxwacom do the following jobs for Wacom tablet: mousedev.c ignores Wacom device as a HID device; usbmouse.c ignores Wacom device as a USB mouse; hid-core.c adds new Wacom devices into the support device list; evdev.c enables Wacom tablet after replugging the tablet.

[jej@ayukawa wacom]$ make First off, if the code does not build, and you cannot chase the problem down yourself, send me a line. If your kernel is much older than 2.4.18, then you may have to resign yourself to the fact that the 2.4.19 drivers are not going to work for you. I would recommend upgrading your kernel. Before installing the drivers, please backup the originals. Then, use the following steps to install the drivers into the proper directories. Use /locate/ as you did for the wacom.o file if necessary. For systems with kernel 2.4 and older than kernel 2.4.22: [jej@ayukawa wacom]$su [jej@ayukawa wacom]#cd src/2.4 [jej@ayukawa 2.4]#cp hid.o /lib/modules/*your-kernel-ver*/kernel/drivers/usb [jej@ayukawa 2.4]#cp usbmouse.o /lib/modules/*your-kernel-ver*/kernel/drivers/usb [jej@ayukawa 2.4]#cp evdev.o /lib/modules/*your-kernel-ver*/kernel/drivers/input [jej@ayukawa 2.4]#cp mousedev.o /lib/modules/*your-kernel-ver*/kernel/drivers/input [jej@ayukawa 2.4]#cp input.o /lib/modules/*your-kernel-ver*/kernel/drivers/input [jej@ayukawa 2.4]#reboot For systems with kernel 2.4.22 or newer: [jej@ayukawa wacom]$su [jej@ayukawa wacom]#cd src/2.4.22 [jej@ayukawa 2.4.22]#cp hid.o /lib/modules/*your-kernel-ver*/kernel/drivers/usb [jej@ayukawa 2.4.22]#cp usbmouse.o /lib/modules/*your-kernel-ver*/kernel/drivers/usb [jej@ayukawa 2.4.22]#cp evdev.o /lib/modules/*your-kernel-ver*/kernel/drivers/input [jej@ayukawa 2.4.22]#cp mousedev.o /lib/modules/*your-kernel-ver*/kernel/drivers/input [jej@ayukawa 2.4.22]#reboot As before with some other distributions, if the files in the kernel module directory are compressed, you'll need to run gzip on the .o files to get .o.gz files. 3.7.4 - Building usbmouse.o, evdev.o, mousedev.o, and hid.o (for kernel 2.6) In the linuxwacom-0.6.4.tar.bz2 file, you will find mousedev.c, usbmouse.c, hid-core.c, and evdev.c files which have special exceptions for wacom. These files are not built by default, so you will need to reconfigure the package and run make again. As for wacom.c, you need to configure the kernel modules (hid and evdev) under your kernel source tree before configuring linuxwacom. *Note:* If your system did not load usbmouse, please DO NOT configure usbmouse. For kernel versions later than 2.6.4, if you are not using Intuos3, you do not need to recompile hid and wacom since they are up to date. On some OS', such as Suse, Fedora Core, and Mandrake, evdev and mousedev are patched with linuxwacom sources. So, your best chance is no need to rebuild the kernel at all.

However, there are code to ignore Wacom tablet as a HID device which are not in the kernel.org source tree. It is required to build those modules/objects if you use a USB mouse. The changes to mousedev are needed if you want to use the /dev/input/mice device in XF86Config, otherwise events from the Wacom mouse will show up on both /dev/input/mice and /dev/input/eventN. The changes to evdev are needed to allow the tablet to continue working correctly after being unplugged/replugged. For kernel 2.6 and later, you almost certainly do not need the usbmouse module because it conflicts with the full usb hid driver, usbhid, which should be used in most cases. For kernel 2.4, I recommend you to build it. The included hid-core.c contains a lot of wacom related code. The included usbmouse.c and mousedev.c have code to ignore wacom tablet as a mouse so wacom driver (wacom.o) can take control of it. The included evdev.c handles the reconnection of a replugged tablet. It works like this: assuming that you have configured the usb tablet and it was up and running. But, by some reason you unplugged the tablet. The inluded evdev.c will enable you to replugged the tablet and use it without reloading the drivers or rebooting the system. If after installing the drivers, the wacom driver is not getting control of the tablet, there is a possibility that your tablet is not listed in any of the driver files. If so, continue on to the next section. Otherwise, if you are up and running, skip to Viewing the Raw Data <#viewdata>. 3.7.6 - Unknown Tablet? To determine whether your device is listed in the driver, we need to determine the device identifier. It can be discovered by doing the following: [root@ayukawa root]# grep -i 56a /var/log/messages | tail -10 Nov 08 21:03:09 ayukawa /etc/hotplug/usb.agent: Setup mousedev for USB product *56a/44/115* Nov 08 21:27:48 ayukawa kernel: usb.c: USB device 2 (vend/prod *0x56a/0x44*) is not claimed by any active driver. In this case, the tablet identifier is 56a/44 (also written 0x56a/0x44). The model is determined by the second number; the Intuos2 12x12 is 0x44 for instance. In the wacom.c file, you will find a table called "wacom_ids." Look for your device identifier. Only the identifiers listed are handled by the wacom driver, so if it is missing, it needs to be added. Also look in hid-core.c. It has a table called "hid_blacklist" which identifies devices to ignore. The code is a little strange, but PENPARTNER is 0x00, GRAPHIRE is 0x10, INTUOS is 0x20, PL is 0x30, and INTUOS2 is 0x40. A table entry like INTUOS2 + 4 would therefore be 0x44. If you've gotten this far, and still cannot get it to work, send me email with your device identifier and as much of an explanation of where things did and did not work as described. I'll see what I can do about at least finding out why it did not work. Then we can go on to solutions. The next section assumes you have things working up to this point. 3.8 - Viewing the Raw Data View the raw data from the tablet, by returning to the /dev/input directory and streaming the data directly from the device. Be patient here because this is where a lot of people are getting stuck. [root@ayukawa usb]# cd /dev/input [root@ayukawa input]# xxd event0 0000000: e65d c33d 597d 0100 0100 4101 0100 0000 .].=Y}....A..... 0000010: e65d c33d 5c7d 0100 0400 0000 b701 2800 .].=\}........(. 0000020: e65d c33d d9bb 0100 0100 4101 0000 0000 .].=......A..... 0000030: e65d c33d dcbb 0100 0400 0000 b701 2800 .].=..........(. (Ctrl-C) First off, you have to move the mouse or tap the pen to get any output. If the tablet is mapped to event0, a continuously data stream will be displayed while you move the mouse or pen on the tablet. Second, you might not get anything at all. Don't panic. This seems to happen occasionally. If absolutely no output occurs, try event1 and event2. It is reported on Fedora Core 2 the event0 used for kernel 2.4 is represented as event2 when switching to kernel 2.6.1-1.65. If no output occurs on those ports, reload the drive: [jej@sasami root]# rmmod wacom [jej@sasami root]# modprobe wacom (or insmod mydir/src/wacom.o) [jej@sasami root]# tail /var/log/messages Nov 08 17:31:31 sasami kernel: usb.c: deregistering driver wacom Nov 08 17:31:34 sasami kernel: usb.c: registered new driver wacom Nov 08 17:31:35 sasami kernel: input0: Wacom Intuos2 12x12 on usb1:2.0 Nov 08 17:31:35 sasami kernel: wacom.c: v1.40-j0.6.3 Vojtech Pavlik The device driver and the tablet occassionally get out of sync with the tablet thinking it's still in HID mode when in fact it should be in "mode 2." By unloading and reloading the driver manually, the initialization code has another opportunity to get it right. Try the /xxd /dev/input/event0/ again. This time, it /should/ work. If not, send me some email. Incidentally, if you have a program running that is connected to /dev/input/event0 (like X or wacdump for instance), it is possible that the tablet will not reattach back to the same event. I have seen the wacom reattach to /dev/input/event1 when unloading and reloading the wacom driver with wacdump running for instance. So, try xxd on event1 or event2 if event0 fails. You should also try running /xxd/ on /dev/input/mouse0. You should get streams of data when the mouse and pen are moved around the surface of the tablet. It is this device that X will look at for mouse movement. Use Ctrl-C to exit xxd. 4.0 - Using wacdump The wacdump program parses and displays raw data from the Linux event subsystem or serial port. It is very handy for verifying that your tablet works without having to hassle with XFree86. Generally, you must be root to run it unless you've set the permissions on the appropriate device such that you can read them. *Building wacdump* Serial users who have been following along will not have built wacdump by this point while USB users should already have it. wacdump is enabled by default in the configure script, so let's do that now: [jej@ayukawa linuxwacom]$ ./configure ... ---------------------------------------- BUILD OPTIONS: wacom.o - no wacdump - *yes* hid.o - no usbmouse.o - no wacom_drv.o - no ---------------------------------------- As shown above, the build options indicate that wacdump will be built. If not, then scroll back through the configuration to see if there aren't any errors or warnings that would explain this. Next, run /make/. The output will be a file called wacdump in the linuxwacom package's src directory. Running /make install/, will install it under /usr/local/bin. *Running wacdump* In the case of USB tablets, this program can run simultaneously with X, but it's best if X has not been configured for the tablet yet. X will not share the serial port with wacdump, so serial users should comment out the wacom InputDevice sections from XF86Config (and/or XF86Config-4) before using. Alternatively, you could move your serial tablet to COM2 and try /dev/ttyS1 instead. The command line usage of wacdump is pretty simple: Usage: wacdump [options] device Options: -h, --help - usage -c, --class device_cls - use specified class (see below) -f, --force device_name - use specified device (see below) -l, --list - list all supported devices -v, --verbose - increase log output; multiple OK -V, --version - display version number --logfile log_file - output log to file Example devices: /dev/input/event0 - usb tablet device /dev/ttyS0 - serial tablet on com1 /dev/ttyUSB0 - serial tablet on USB adapter Supported device classes: serial, usb Supported device names: serial: art, art2, dig, dig2, pp, gr, pl, int, int2, c100 usb: pp, gr, gr2, int, int2, pl, vol Older versions of wacdump assumed the device to be /dev/input/event0. This is now deprecated. You should instead specify which device to use on the command line directly. If you get an end-of-file error or the device does not exist, then the wacom may be attached to a different event. Serial users may experience a timeout error which indicates that either the tablet is not responding or XFree86 has it open. Access denied errors probably indicate that you are not root <#root>. If you get different types of errors, let me know so we can get them documented. Serial users are advised that now is a good time to plug in your tablet, if you haven't already. Let's run wacdump. Here are some command line examples: [jej@ayukawa src]$ ./wacdump /dev/input/event0 # typical USB tablet [jej@ayukawa src]$ ./wacdump /dev/input/event1 # USB tablet on event1 Here is a sample command line for Tablet PC. Since Tablet PC normally doesn't explicitly set its Wacom digitizer to a serial port, you probably need to run setserial. /It is not necessary to run setserial for standard Wacom tablets./ The IO port may be different for your Tablet PC. [jej@ayukawa src]$ setserial /dev/ttyS2 ioport 0x93f8 autoconfig [jej@ayukawa src]$ ./wacdump -f c100 /dev/ttyS2 # Wacom digitizer on fake COM3 When you run wacdump, it will attempt to initialize and query the tablet. For a number of reasons, it may not display anything immediately, but if you place a mouse or pen near the surface, the screen should update. You will then be presented with a screen similar to the following: wacdump v0.4.0 MODEL=Wacom Intuos2 12x12 ROM=1.1-5 CLS=USB VNDR=Wacom DEV=Intuos2 SUB=XD-1212-U TOOLTYPE=NONE SERIAL=0x00000000 IN_PROX=+00000 (+00000 .. +00000) BUTTON=+00000 (+00000 .. +00000) POS_X=+00000 (+00000 .. +30480) POS_Y=+00000 (+00000 .. +31680) ROT_Z=+00000 (-00900 .. +00899) DISTANCE=+00000 (+00000 .. +00015) PRESSURE=+00000 (+00000 .. +01023) TILT_X=+00000 (+00000 .. +00127) TILT_Y=+00000 (+00000 .. +00127) ABSWHEEL=+00000 (+00000 .. +01023) RELWHEEL=+00000 (-00001 .. +00001) THROTTLE=+00000 (-01023 .. +01023) LEFT= MIDDLE= RIGHT= EXTRA= SIDE= TOUCH= STYLUS= STYLUS2= The top portion identifies the tablet, and unless you specifically override the device type with the -f option, it should be auto-detected from the tablet directly. In this case, the model is XD-1212-U, a USB Intuos2 12x12. The next section describes the dynamic attributes of the tablet, including the current position of the pointer, the type of tool in proximity to the surface, its pressure, and tilt. Some tablets provide serial numbers for their styluses. When a button is pressed, the button heading will change to something like "STYLUS=DOWN". Some tablet tools report wheel movements as single increments forward and reverse, while others provide absolute positions. The 4D mouse has a throttle instead of a wheel. All three cases are reported independently. Different tablets will have different options. Here is the lowly ArtPadII for comparison. wacdump v0.4.0 MODEL=Wacom ArtPadII 4x5 ROM=1.3-6 CLS=Serial VNDR=Wacom DEV=ArtPadII SUB=KT-0405-R TOOLTYPE=NONE IN_PROX=+00000 (+00000 .. +00000) BUTTON=+00000 (+00000 .. +00000) POS_X=+00000 (+00000 .. +06400) POS_Y=+00000 (+00000 .. +04800) PRESSURE=+00000 (+00000 .. +00255) LEFT= MIDDLE= RIGHT= EXTRA= SIDE= TOUCH= STYLUS= STYLUS2= Notice that this tablet has no tilt, and the pressure range is considerably reduced. This version of wacdump does not distinguish between tablets with mice, so the left, right, and middle buttons are present, even though the tablet itself has no mouse. This will likely change in the future. *Out of Range Values* If you get X and Y coordinates, pressures, or tilt values outside of the ranges specified, please let me know as soon as possible. Bad range values can prevent the XFree86 driver from working correctly. It is helpful if you can determine the true maximum values and send them along with your tablet type and model number. A text-mode copy of the screen would be even better. 5.0 - Configuring XFree86 Two steps must be completed to get X to recognize your tablet. First, you need to add some lines to XF86Config to inform X of the tablet's existence. Second, you need to update the XInput driver that pertains to the tablet since the one that ships with XFree86 is not very functional. Neither driver holds a candle to the windows driver though, so you'll have to take what you get for the time being. Updates to the XFree86 driver are available in the stable and beta releases on the Downloading the Code <#download> page. You may also check Lepied's Wacom Site which has source code up to version 26 as of this writing. 5.1 - Adding the InputDevices The X Window system identifies the stylus and eraser on your tablet as XInput devices. Applications that want to know the absolute position of your stylus can request that information directly, and this generally bypasses whatever the mouse happens to be doing at the time. This design is not without problems though. For one, changing your setup or adding a new tool requires making changes to the XF86Config file and restarting X. This should be fixed in the future. For now however, add the InputDevice sections to your XF86Config file. This assumes you are running XFree86 4.x. On some distributions, this file is called XF86Config-4. Notice that the serial and USB configurations are different, so only include the appropriate lines. For Tablet PCs, options "Device" and "ForceDevice" should be included. You should also change the device (e.g. ttyS0) to the correct one for your tablet; the default serial and USB devices are given. All the new driver options are listed in the manual page below. Section "InputDevice" Driver "wacom" Identifier "cursor" *Option "Device" "/dev/ttyS0" # SERIAL ONLY* *Option "Device" "/dev/input/event0" # USB ONLY* Option "Type" "cursor" *Option "USB" "on" # USB ONLY* *Option "ForceDevice" "ISDV4" # Tablet PC ONLY* EndSection Section "InputDevice" Driver "wacom" Identifier "stylus" *Option "Device" "/dev/ttyS0" # SERIAL ONLY* *Option "Device" "/dev/input/event0" # USB ONLY* Option "Type" "stylus" *Option "USB" "on" # USB ONLY* *Option "ForceDevice" "ISDV4" # Tablet PC ONLY* EndSection Section "InputDevice" Driver "wacom" Identifier "eraser" *Option "Device" "/dev/ttyS0" # SERIAL ONLY* *Option "Device" "/dev/input/event0" # USB ONLY* Option "Type" "eraser" *Option "USB" "on" # USB ONLY* *Option "ForceDevice" "ISDV4" # Tablet PC ONLY* EndSection Section "InputDevice" Driver "wacom" *Identifier "pad" # Intuos3 Tablet ONLY* *Option "Device" "/dev/ttyS0" # SERIAL ONLY* *Option "Device" "/dev/input/event0" # USB ONLY* Option "Type" "pad" *Option "USB" "on" # USB ONLY* EndSection The above four sections identify the cursor, stylus, eraser, and pad devices to XInput. Notice that all four reference the same device /dev/ttyS0 or /dev/input/event0 depending on whether its a serial or USB tablet. The configuration options listed by your system's man page is way out of date. Below is an updated wacom man page. We will commit this page to XFree86 CVS repository as soon as we get enough positive feedbacks from users like you. WACOM(4x) XFree86 WACOM(4x) NAME wacom - Wacom input driver SYNOPSIS Section "InputDevice" Identifier "idevname" Driver "wacom" Option "Device" "devpath" ... EndSection DESCRIPTION wacom is an XFree86 input driver for Wacom devices. The wacom driver functions as a pointer input device, and may be used as the X server's core pointer. SUPPORTED HARDWARE This driver supports the Wacom IV and Wacom V protocols. Preliminary support is available for USB devices on some Linux platforms. CONFIGURATION DETAILS Please refer to XF86Config(5x) for general configuration details and for options that can be used with all input drivers. This section only covers configuration details specific to this driver. Multiple instances of the Wacom devices can cohabit. It can be useful to define multiple devices with different active zones. Each device supports the following entries: Option "Type" "stylus"|"eraser"|"cursor"|"pad" sets the type of tool the device represent. This option is mandatory. "pad" is for Intuos 3 Tablet Menu Strip only. Since all Intuos3 has Menu Strip(s), "pad" is mandatory for Intuos 3 if your application uses Menu Strip features. Option "Device" "path" sets the path to the special file which represents serial line where the tablet is plugged. You have to specify it for each subsection with the same value if you want to have multiple devices with the same tablet. This option is mandatory. Option "USB" "on" tells the driver to dialog with the tablet the USB way. This option is only available on some Linux platforms. Option "ForceDevice" "ISDV4" tells the driver to dialog with the tablet the Tablet PC way. Tablet PC is a serial tablet using a special Wacom IV protocol, called ISDV4 protocol. Option "DeviceName" "name" sets the name of the X device. Option "Suppress" "Inumber" sets the position increment under which not to transmit coordinates. This entry must be specified only in the first Wacom subsection if you have multiple devices for one tablet. If you donâ??t specify this entry, the default value, which is 2, will be used. To disable suppression, the entry should be specified as 0. Option "Mode" "Relative"|"Absolute" sets the mode of the device. Option "Tilt" "on" enables tilt report if your tablet supports it (ROM version 1.4 and above). If this is enabled, multiple devices at the same time will not be reported. Option "TopX" "number" X coordinate of the top corner of the active zone. Option "TopY" "number" Y coordinate of the top corner of the active zone. Option "BottomX" "number" X coordinate of the bottom corner of the active zone. Option "BottomY" "number" Y coordinate of the bottom corner of the active zone. Option "ButtonsOnly" "on" disables the device's motion events. Option "ButtonM" "N" reports a button N click when button M is pressed, where M is one of the wacom supported button numbers, it can be 1 to 16 and N can be an integer between 1 and 19. The default value for button M is M. When N is less than 17, button M is assigned to the function of button N. When N is 17, button M is a left-double-click. When N is 18, button M is ignored, i.e., no button event will be reported when clicking on button M. When N is 19, button M is assigned to Mode Toggle, switching between relative and absolute mode, which is especially useful to switch windows in a multi- monitor environment. Option "TPCButton" "on" enables the stylus buttons as Tablet PC buttons, i.e., reports stylus button event only when its tip is pressed. Option "Speed" "Rspeed" sets the cursor's relative movement speed to Rspeed. The default value is 1.0. A Rspeed greater than 1.0 will speed up the cursor's relative movement. A Rspeed less than 1.0 but greater than 0 will slow down the cursor's relative movement. A Rspeed too close to 0 is not recommanded. Option "Twinview" "horizontal"|"vertical"|"none" sets the orientation of TwinView to map the tablet to the whole desktop or a specific screen if "ScreenNo" option is added. If you want to map the tablet to only one screen but freely move from one screen to the other, you should NOT add this option. The default is "none". Option "TVResolution" "res1,res2" specifies different resolutions for the two screens in TwinView setup. For example, if the resolution of screen 1 (res1) is 1024x768 and screen 2 (res2) is 1280x1024, the option will be set to: Option "TVResolution" "1024x768,1280x1024" It is unnecessary to add this option if your screens are displaying in the same resolutions. Option "ScreenNo" "n" In a multi-monitor environment, specifies the screen number in which the cursor can move. Option "Rotate" "CW"|"CCW"|"NONE" rotates the Tablet PC's screen orientation, clockwise or anti-clockwise. The default is "NONE". Option "PressCurve" "x1,y1,x2,y2" sets pressure curve by control points x1, y1, x2, and y2. Their values are in range from 0..100. The input for linear curve (default) is "0,0,100,100"; slightly depressed curve (firmer) might be "5,0,100,95"; slightly raised curve (softer) might be "0,5,95,100". Option "KeepShape" "on" When this option is enabled, the active zone begins according to TopX and TopY. The bottom corner is adjusted to keep the ratio width/height of the active zone the same as the screen while maximizing the area described by TopX, TopY, BottomX, BottomY. Option "DebugLevel" "number" sets the level of debugging info reported. There are 11 levels, specified by the integers between 1 and 11. Option "Serial" "number" sets the serial number associated with the physical device. This allows to have multiple devices of the same type (i.e. multiple pens). This option is only available on wacom V devices (Intuos). To see which serial number belongs to a device, you have to set the DebugLevel to 6 and watch the output of the X server. Option "Threshold" "number" sets the pressure threshold used to generate a button 1 events of stylus devices for some models of tablets (Intuos and Graphire).

AUTHORS Frederic Lepied 4.4.0 Version WACOM(4x) 5.2 - Mouse1 This section largely deals with interaction problems between the mouse1 device, PS/2 mouse, and USB tablets. Serial users can ignore this part. If you have a USB mouse or PS/2 mouse and are also using a USB tablet, there are two solutions here for you: you may either change your mouse1 or PS/2 InputDevice section to something other than /dev/input/mice or build mousedev.o from this project for your kernel, which will ignore Wacom tablets as USB mice. The wacom tablet appears as a mouse to the Linux kernel, and consequently, the "mice" device combines the input from all your mice, including the tablet. This will not give you the behavior you want. A better choice is to specify the precise USB device or PS/2 mouse from which you want to receive mouse events, namely /dev/input/mouse0 or /dev/input/mouse1 or /dev/psaux. This is known to have happened for a Logitech USB mouse on RedHat 8.0. If you do not have a USB mouse, adding the Mouse1 device is /probably not something you want to do/. Despite this, Redhat's Anaconda program will do it for you if you boot the machine with the tablet plugged in. You'll need to be careful about this. When you use the mouse1 input device, the data flows from the USB wacom kernel driver, through the event subsystem, down into the mousedev driver, out the /dev/input/mouse0 device, and finally into the XInput mouse driver. You effectively lose all your absolute positioning information because the mousedev driver converts it into relative data. Additionally, the XFree86 wacom driver does not get control of the cursor because mouse1 is providing those events. Therefore, if you have a Mouse1 section, leave it. Redhat 8.0 at least, expects it to be there; however, if you do not have a USB mouse and you are using a USB tablet, you will not be using this section, so make certain that it is commented out of the ServerLayout section covered next. There is one exception however. If you have no other mouse device in your ServerLayout section, /do not/ remove Mouse1. XFree86 will not start without at least one core pointer, and the tablet does not count unless it is specifically identified as a "CorePointer" rather than merely "SendCoreEvents." 5.3 - ServerLayout The ServerLayout section describes what devices the X server will use. Modify the ServerLayout section to reflect the new devices. Make certain to comment out the Mouse1 device if determined necessary from the previous page. Section "ServerLayout" Identifier "Default Layout" Screen 0 "Screen0" 0 0 InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" *InputDevice "cursor" "SendCoreEvents" InputDevice "stylus" "SendCoreEvents" InputDevice "eraser" "SendCoreEvents" InputDevice "pad" "SendCoreEvents" # For Intuos3 tablet only* #InputDevice "Mouse1" "SendCoreEvents" #InputDevice "tablet" "SendCoreEvents" EndSection This section determines which devices are actually used by the server. In the case above, the cursor, stylus, and eraser devices are selected while the mouse1 and tablet devices are commented out. At present, this is the correct configuration for proper operation of the tablet whether you are using the beta package or the production package. You can configure one of your Wacom devices as a Core Pointer if you don't have a regular mouse on your system. However, you lose the Wacom specific functions, such as pressure sensitivity and absolute mode when you use that device. You have completed the XF86Config file changes. By aware that if you reboot your computer with the Wacom plugged in and Redhat's Anaconda program notices, it will treat the tablet as a USB mouse and reconfigure this file incorrectly. You may need to go back and check the file to ensure that everything is still correct afterwards. Rebooting with the device detached seems to reverse the process, but again, you should check the file to be certain. My recommendation is to tell Anaconda to ignore the tablet until the device detection works properly. 5.4 - Updating wacom_drv.o There are a number of wacom_drv.o files about. XFree86 is shipping version 23. Redhat 8.0 is shipping version 25. Lepied's page has the source code for 26, but the binary identifies itself as 23ss1. The Downloading the Code <#download> page currently offers source and binary for 26-j0.6.3 in the stable package and 26-j0.5.26 in the beta version. In total, I recommend using the drivers in the packages that I provide since they correspond with what is shown in this document. Any new functionality that gets added will be built on top of these files as well. Note: the binary wacom_drv.o file is located in the prebuilt directory of the stable and beta packages. Instructions for rebuilding from source are available in the Appendix under Building wacom_drv.o From Scratch <#builddrv> if you are a developer yourself or the binary is not compatible with your system. With that said, locate and replace wacom_drv.o. Using /locate/, we find the driver in the XFree86 tree. This directory is pretty standard, so it is unlikely that your file will be located elsewhere. Note the assumption is that you are using XFree86 4.x. Anything from the 3.x version probably won't work. [root@ayukawa root]# locate wacom_drv.o /usr/X11R6/lib/modules/input/*wacom_drv.o* [root@ayukawa root]# cd /usr/X11R6/lib/modules/input [root@ayukawa input]# cp *wacom_drv.o* /home/jej/src/wacom/*wacom_drv_old.o* [root@ayukawa input]# cp /home/jej/src/wacom/prebuilt/*wacom_drv.o_vxkvk wacom_drv.o* where vx stands for your XFree86 version and vk stands for your kernel version. The old file is copied away, and replaced with the newer version. The binary modules are presently built on a Redhat 8.0 system using gcc 3.2 under glibc. This should work for most, if not all, major distributions. If it does not load on yours, please let me know. 5.5 - Restart X Finally, restart X. You may wish to do this from runlevel 3 for testing purposes. [root@ayukawa root]# init 3 ...processes starting and stopping... [root@ayukawa root]# startx If the X server dies, you can always back-out the changes to the XF86Config file and try again. Worse case, copy the wacom_drv_old.o file back to its original place. But first, look at the XFree86 log file for clues. You might want to do this even if everything works correctly. When things are running right, the following lines appear in my log file. [root@ayukawa root]# grep -i wacom /var/log/XFree86.0.log (II) LoadModule: "wacom" (II) Loading /usr/X11R6/lib/modules/input/wacom_drv.o (II) Module wacom: vendor="The XFree86 Project" (II) Wacom driver level: *26-j0.6.3* $ (II) XINPUT: Adding extended input device "eraser" (type: Wacom Eraser) (II) XINPUT: Adding extended input device "stylus" (type: Wacom Stylus) (II) XINPUT: Adding extended input device "cursor" (type: Wacom Cursor) (==) Wacom Kernel Input device name: "Wacom Intuos2 12x12" (==) Wacom tablet maximum X=30480 maximum Y=30480 X resolution=0 Y resolution=0 suppress=0 (==) Wacom Cursor top X=0 top Y=0 bottom X=30480 bottom Y=30480 (==) Wacom Stylus top X=0 top Y=0 bottom X=30480 bottom Y=30480 (==) Wacom Eraser top X=0 top Y=0 bottom X=30480 bottom Y=30480 Notice the driver version 26-j0.6.3 above. This is the new stable wacom_drv.o driver. The beta driver is currently 26-j0.5.26. First things first, you should lift the mouse off the tablet and place it back down. This seems to help reset things internally. When you replace the mouse, the cursor should jump to that portion of the screen. If everything is working correctly, the mouse should work in absolute mode with the four corners of the tablet corresponding with the four corners of the screen. If the cursor stops short of an edge, then the kernel driver limits are probably incorrect. Please let me know so that I can update the driver. Next, remove the mouse and try using the eraser end of the stylus. Hovering over the surface of the tablet should move the cursor. Touching the eraser tip to the surface should generate a click. If you invert the pen and use the stylus tip, you should get a similar result. If the pen tip generates spurious touch events, you will need to increase the threshold value in the InputDevice section. Wacdump is useful for determining the appropriate value. Lastly, if you would like more logging, the parameter "DebugLevel" can be set to values between 1 and 11, with 11 being way too much, and 1 being fairly useful. 5.6 - Check the Pointer Status You can check the XInput pointer status by using /xsetpointer/ as below. The man page states that calling xsetpointer with the name of a particular device will set it as the primary pointing device. So far, that has not been the case in my experience; however, that is the subject of current development, so try it, and if it doesn't work, stay tuned. [root@ayukawa log]# xsetpointer -l "eraser" [XExtensionDevice] "stylus" [XExtensionDevice] "cursor" [XExtensionDevice] "Mouse0" [XPointer] "keyboard" [XKeyboard] 6.0 - Using xidump The xidump program is similar to wacdump, but it parses and displays event data from the XFree86 XInput extension rather than from the tablet itself. This is useful for seeing what programs like gimp and gsumi are receiving from X. Presently, xidump will display proximity and motion events for the stylus, cursor, and eraser input devices. xidump supports different display modes with "curses" and "raw" modes already implemented and a GTK-based graphical mode in the works. The curses mode is probably the most useful in terms of verifying that the tablet is functioning correctly in the XFree environment; however, the raw mode has the additional benefit of being able to verify the order, timing, and history of events. Since xidump uses the same XInput interface that gimp and gsumi use to get tablet data, the values displayed in xidump should be identical to what they are receiving. If you are having trouble with pressure in gimp, chances are that xidump will demonstrate the same problem. xidump does not require root access to use. *Building xidump* xidump builds by default so if you've configured and built the project in previous steps, you probably have it already. If not, we can build it now. xidump requires the XLib and XInput header files to be present on the system. On Redhat 8.0, these files are located in the XFree86-devel RPM package. Other distributions may be organized differently, and people who build X from source probably get them by default. When configuring, check that XLib is detected in the build environment, and if not, refer to the warnings and "checking for" messages for additional clues. The preferred display mode for xidump uses ncurses. To compile it, you will need the ncurses header files. On Redhat 8.0, these files are located in the ncurses-devel package. Without ncurses, xidump defaults to raw mode automatically. [jej@ayukawa linuxwacom]$ ./configure checking for XLib include directory... *found* checking for XLib header files... *found* checking for ncurses.h... *yes* ... ---------------------------------------- BUILD ENVIRONMENT: ... *XLib - yes* *ncurses - yes* ... BUILD OPTIONS: ... *xidump - yes* ... ---------------------------------------- The configuration above indicates that the XLib and ncurses header files were found and xidump will be built. If ncurses.h is not found, xidump will still build, but it will also warn you that ncurses will not be available. If you encounter warnings, it is most likely that your development environment is missing some packages. When you run /make/, the xidump program will be built along with any other programs that are specified in the build options. The output file is called 'xidump' and is located in the linuxwacom package's src directory. It is installed by running /make install/. *Running xidump* xidump takes one argument, the input device specified in your XF86Config file. Ordinarily, this would be either stylus, cursor, or eraser, but you can get a complete list by running xidump with the list option '-l'. xidump has the additional feature of dumping all the device capabilities by specifying the verbose option '-v'. Both are demonstrated below. [jej@ayukawa src]$ ./xidump -l eraser extension stylus extension cursor extension Mouse0 disabled keyboard keyboard [jej@ayukawa src]$ ./xidump -l -v eraser eraser extension key: min=8, max=39, num=32 btn: num=1 val: axes=6 mode=abs buf=0 axis[0]: res=0, max=0, max=30480 axis[1]: res=0, max=0, max=30480 axis[2]: res=39, max=0, max=1023 axis[3]: res=1, max=-64, max=63 axis[4]: res=1, max=-64, max=63 axis[5]: res=1, max=0, max=1023 In the first dump, we see the eraser, stylus, and cursor with the additional Mouse0 pointer and keyboard. Only the first three are "extension" devices. Using xidump on the keyboard or mouse pointer will generate an error since neither are XInput devices. The second dump shows the capabilities of the eraser device including the number of keys (32), buttons (1), and axes (6). It also shows the mode to be absolute. In order, the axes are: x, y, pressure, tilt-x, tilt-y, and wheel. When the cursor is used, axis 3 becomes z-rotation instead of tilt-x. You should be aware that xidump and gimp must take ownership of the device in order to get real-time data. This creates a conflict if you are running both of them simultaneously. gimp is the more clever of the two programs in that it only "grabs" the input device if you are hovering over the gimp drawing window. xidump is less friendly. In order to display the absolute position across the entire screen, it creates a small "listening window," grabs the device immediately, and does not release it until you quit the program. Neither program should fail, but you will not be able to draw in gimp and run xidump at the same time if they are both using the same input device. We will run xidump in raw mode for the first time to see the stylus events directly. A small window will appear on the desktop while xidump runs; you can safely ignore it. Closing it will kill the application. [jej@ayukawa src]$ ./xidump -u raw stylus 14.56291895: Proximity In 14.56305595: Motion: x= +5978 y=+28728 p= 0 tx= +64 ty= +64 w= +0 ... 16.87158095: Motion: x= +4941 y=+27842 p= 225 tx= +41 ty= +67 w= +0 16.87164395: Button: 1 DOWN 16.87169595: Motion: x= +4964 y=+27844 p= 398 tx= +42 ty= +66 w= +0 ... 17.27328395: Motion: x= +5261 y=+27543 p= 3 tx= +48 ty= +64 w= +0 17.27334395: Button: 1 UP 17.27515995: Motion: x= +5348 y=+27451 p= 4 tx= +48 ty= +63 w= +0 ... 17.35933795: Motion: x= +7089 y=+27061 p= 4 tx= +48 ty= +63 w= +0 17.37444395: Proximity Out The timestamp on the left is seconds elapsed; the next field is the event type. Mostly, you will encounter motion events although I've trimmed many of them out of this listing. As you can see from the above, the first line is a "proximity in" event which indicates the stylus came in range of the tablet. The last event was a "proximity out." At 16.87 seconds, I tapped the stylus to the tablet surface as recorded by the "Button: 1 DOWN" and subsequent "UP" message. Raw mode is useful for verifying the order and timing of messages, but is not particularly clean. The ncurses mode works much better. [jej@ayukawa src]$ ./xidump stylus InputDevice: stylus Valuators: Absolute Axes: 6 Buffer: 0 x-axis y-axis pressure x-tilt y-tilt wheel data: +10826 +09919 +00004 +00058 +00065 +00000 min: +00000 +00000 +00000 -00064 -00064 +00000 max: +30480 +30480 +01023 +00063 +00063 +01023 res: +00000 +00000 +00039 +00001 +00001 +00001 Proximity: IN Focus: Buttons: 1-DOWN Keys: All of the ranges are display above, include their resolutions which as far as I know are not normally used.

The future GTK mode will be available in the same manner. Adding the --verbose option increases the amount of output, and when used in conjunction with --list, displays the device capabilities. *Out of Range Values* At present, we are discovering a number of problems with out-of-range values. Rest assured, we are looking into it, so if you encounter them yourself, you might consider check the mailing list for similar problems, and if your problem is unique, let us know. When the driver is behaving better, I'll increase the priority of this class of problem. Until then, you'll probably just get a message back saying "sorry, and yes, we know." The most serious problem seems to be with runaway pressure settings, so those will get investigated first. 7.0 - Using xsetwacom The xsetwacom is a command-line Wacom driver configuration tool. It changes the pressure sensitivity, click threshold, button functions, cursor mode and speed, and much more without having to manually modify XF86Config file. However, it is reported that there are systems on which you can not run xsetwacom due to some XFree86 interface error. We did not figure out the root cause of this problem yet. Please check Success Stories <#success> page to see if your system is in question. If it is, you'll have to add the configuration options to your /etc/X11/XF86Config file. Please refer Configuring XFree86 <#x11> for details. *Building xsetwacom* xsetwacom uses libwacomcfg.so to communicate with Wacom XFree86 driver, wacom_drv.o. So, libwacomcfg.so should be built and installed. libwacomcfg.so relies on Xlib. In the configure script, it will default the Xlib path to /usr/X11R6. If your Xlib is not installed under /usr/X11R6, you'll need to specify the path (dir) by /--with-xlib=dir/. Let's see what we get from configure: [jej@ayukawa linuxwacom]$./configure ... ---------------------------------------- BUILD ENVIRONMENT: architecture - i686 linux kernel - yes 2.4 module versioning - yes -DONFIG_MODVERSIONS -DMODVERSIONS -include /usr/src/linux/include/linux/modversions.h kernel source - yes /usr/src/linux XFree86 - no XLib - yes /usr/X11R6 TCL - yes /usr TK - yes /usr ncurses - yes GTK - 2.0.6 BUILD OPTIONS: wacom.o - no wacdump - yes xidump - yes libwacomcfg - yes libwacomxi - yes xsetwacom - yes hid.o - no usbmouse.o - no evdev.o - no mousedev.o - no input.o - no tabletdev.o - no wacom_drv.o - no ---------------------------------------- As shown above, the build options indicate that libwacomcfg and xsetwacom will be built. If not, then scroll back through the configuration to see if there aren't any errors or warnings that would explain this. Next, run /make/. The output will be stored in the linuxwacom package's src and src/.libs directory. They will be installed by running /make install (you need to switch to superuser to run this command)/. If wacom_drv.o was running while installing xsetwacom, xsetwacom can be launched immediately after /make install/ and /exit (switch back to your own account)/. If wacom_drv.o is installed by the same /make install/ as xsetwacom is, restarting X server is required to use the newly built wacom_drv.o. We strongly recommand to build and install the wacom_drv.o and xsetwacom from the same release package since the out of sync wacom_drv.o and xsetwacom may crash your X server. *Running xsetwacom* [jej@ayukawa linuxwacom]$xsetwacom Usage: xsetwacom [options] [command [arguments...]] Options: -h, --help - usage -v, --verbose - verbose output -V, --version - version info -d, --display disp_name - override default display Commands: list [dev|param] - display known devices, parameters set dev_name param [values...] - set device parameter by name The most used xsetwacom command is /xsetwacom set dev_name param [values...]/, where param is an option which will be set to values in wacom_drv.o after excuting xsetwacom. To better understand the use of this command, let's see some examples. Assume that you use /Stylus/ as your Wacom tool's Identifier, which is considered is considered as dev_name in xsetwacom command. If you want to change /Stylus's/ mode from absolute (default) to relative, then: [jej@ayukawa linuxwacom]$xsetwacom set Stylus mode relative If you want to change button 2 to left-double-click, then: [jej@ayukawa linuxwacom]$xsetwacom set Stylus button2 17 If you want to set the pressure sensitivity a bit softer, then: [jej@ayukawa linuxwacom]$xsetwacom set Stylus PressCurve 0,15,85,100 If you want the buttons behave the Tablet PC way, i.e., sending button event only when button1 (the tip) is pressed, then: [jej@ayukawa linuxwacom]$xsetwacom set Stylus TPCButton on Below is a list of the parameters and their values used by /xsetwacom set/ command: param [values...] results ------------------------------------------------------------------ Mode Relative|Absolute sets the mode of the device TopX integer sets the X coordinate of the top corner of the active zone TopY integer sets the Y coordinate of the top corner of the active zone BottomX integer sets the X coordinate of the bottom corner of the active zone BottomY integer sets the Y coordinate of the bottom corner of the active zone Button/M/ integer (1 - 16) sets button /M/ to button integer click Button/M/ 17 sets button /M/ to left-double-click Button/M/ 18 ignores button /M/ click Button/M/ 19 sets button /M/ to Mode Toggle PressCurve i1,i2,i3,i4 sets the pressure bezier curve, where i1+i4=100; i2+i4=100 DebugLevel integer (1 - 12) sets the level of debugging trace SpeedLevel integer (1 - 11) sets relative cursor movement speed ClickForce integer (1 - 21) sets tip/eraser pressure threshold xyDefault resets the bounding coordinates to default in tablet units gimp on|off turns on/off Gimp support in Xinerama-enabled environment mmonitor on|off turns on/off across monitor movement on multi-monitor desktop TPCButton on|off turns on/off the buttons as Tablet PC buttons ------------------------------------------------------------------ The xsetwacom commands can be added to the .xinitrc under your home directory so next time when you login as yourself, the driver will be set to the options you choose.

To see what's under your home directory, use /ls -al ~/. 8.0 - Using wacomcpl The wacomcpl is a graphic Wacom driver configuration tool. It changes the pressure sensitivity, click threshold, button functions, cursor mode and speed without having to manually modify XF86Config file. For Cintiq and Tablet PC users, it is also a tool to calibrate the tablet. wacomcpl should be launched when you login as yourself since .xinitrc, a file under your home directory, will be updated each time you run wacomcpl. The .xinitrc stores the preferences you selected through wacomcpl for your next login. The goal is to give each user a chance to use his/her own preference on a shared system. If your system doesn't execute .xinitrc at login, after exiting from wacomcpl, you will need to copy those xsetwacom commands in .xinitrc into the startup script (.bashrc, .cshrc, .profile, etc.) that your system launches. However, it is reported that there are systems on which can not run wacomcpl due to some XFree86 interface error. We did not figure out the root cause of this problem yet. Please check Success Stories <#success> page to see if your system is in question. If it is, you'll have to add the configuration options to your /etc/X11/XF86Config file. Please refer Configuring XFree86 <#x11> for details. *Building wacomcpl* wacomcpl is written in tcl/tk. It uses libwacomxi.so and xsetwacom to communicate with Wacom XFree86 driver, wacom_drv.o. So, to run wacomcpl, tcl/tk should be installed, libwacomxi.so and xsetwacom should be built and installed. libwacomxi.so and xsetwacom are enabled by default in the configure script. By default, the script will assume that tcl/tk is installed under /usr. That is, tcl.h and tk.h should be under /usr/include; libtcl.so.0 and libtk.so.0 should be under /usr/lib.

If wacom_drv.o is installed by the same /make install/ as wacomcpl is, restarting X server is required to use the newly built wacom_drv.o. We strongly recommand to build and install the wacom_drv.o and wacomcpl from the same release package since the out of sync wacom_drv.o and wacomcpl may crash your X server. 9.0 - Working With Gimp It has been suggested that gimp should be recompiled from source (v1.2.3) on Mandrake 9.0. This does not seem to be true for Redhat 8.0. It is also reported that Slackware didn't configure gtk with xinput support. So, you may need to rebuild gtk with ./configure --with-xinput=xfree on Slackware. Bring up /gimp/ and select "File|Dialogs|Input Devices". You will see a drop-down list with all three devices present. After enabling them, you can see their respective statuses by calling up "File|Dialogs|Device Status". It has been recommended that the devices be set to "Screen" mode rather than "Window" due to a bug in Gimp which causes it to crash unexpectedly. I have successfully been able to use gimp with several different pens, including the tips and erasers. Tilt does not appear to be used by gimp at present, but pressure works fine. If the pressure is too coarse, or doesn't kick in until too late, you may need to lower your threshold value. The pressure curve setting can be changed through graphic tool, wacomcpl, and command line tool, xsetwacom. Also, a useability note with Gimp: Each input device (stylus,cursor,eraser) has a completely different set of attributes in Gimp, and in theory, you can even assign a unique serial number to different pens to get even more granularity. You will experience this when you try to use your eraser for the first time. Rather than selecting the eraser tool, you get the rectangle selection tool instead. This is by design, believe it or not. Gimp does not care that its an eraser, just that it's not the pen you were just using. If you choose the eraser tool now, it will remember that for the next time you try to use it. On the plus side, you can set the eraser to be anything, including the Airbrush tool or Clone tool. One tablet user has pointed out that deleting his .gimp directory and rerunning gimp was necessary before his airbrush worked correctly. If you are having trouble, it's worth a shot. Good luck! 10.0 - Contacts Ping Cheng can be contacted at the following email address: pingc@wacom.com . 11.0 - Appendix This section is for everything that is either not critical or simply too complex to describe in the document above without becoming overly distracting. 11.1 - Building wacom_drv.o From Scratch Introduction I should tell you out-right that this is a time consuming process. Why would you want to do this? Two reasons. One, you are a developer and need to make changes to the source code directly. Two, your distribution uses c libraries or configuration options that are not compatible with the wacom_drv.o file that I provide. People running libc5 for instance, would need to build their own driver. Timothy Klein has submitted a brief howto for compiling on Debian Stable which is still running XFree86 4.1 as of this writing. It covers steps one through four of this document, and a savvy developer should be able to figure out step five on his own. If someone solves step five and generates a patch to Makefile.am, I'll see what I can do about getting it into the configuration script. That document is on the Building wacom_drv.o On Debian Stable <#debwcmdrv> page. You will need the X source code to rebuild the wacom_drv.o driver. The build configuration for X generates a number of header files that are necessary but not installed by default on most distributions. Consequently, you will need to not only get the source, but build it, practically in its entirety. Then, after all that, the configure script can be instructed to hook into the X build tree and rebuild wacom_drv.o at any time without having to rebuild X again. Since I am running Redhat 8.0 and cannot really pull down the original XFree86 4.2.0 source code, compile it, and expect it to work on my system, I need to instead use the source RPM provided by Redhat. If you choose to go this route, I provide pretty detailed instructions for making this work. If your distribution works differently, or you are using Gentoo where most everything is source code by default, you'll need to handle this as best as possible according to your particular situation. Step One: Get The Source On Redhat 8.0, I discovered the version number for my currently installed XFree86 packages by running /rpm -q XFree86/. This reported version 4.2.0-72, therefore the source package is XFree86-4.2.0-72.src.rpm. I downloaded the package from Redhat directly and installed it to the system as follows: [root@sen src]# rpm -ivh XFree86-4.2.0-72.src.rpm 1:XFree86 ########################################### [100%] This installs a number of files to the /usr/src/redhat directory, particularly in the SOURCES and SPECS subdirectories. Other distributions undoubtedly install elsewhere. Look for the XFree86.spec file which should be located in the SPECS directory. This file contains all the information necessary to patch the orginal XFree86-4.2.0 source code to the level that Redhat is distributing in their regular binary package. The source code and patch files are located in SOURCES. Step Two: Build the Source This step describes how to build the source from the RPM itself. If you are building from some other mechanism, I honestly cannot offer much assistance since I generally don't build my X system from scratch. If you'd like to write up a short section on building the server for your particular distribution, I would be happy to include it here. Next, you don't actually have to build the entire thing. The point at which the xf86Wacom.c driver can be built however, is not until somewhere in the middle of the build process. The driver depends on a number of header files that are created dynamically so until they are generated, wacom_drv.o cannot be compiled. My solution was to open a separate terminal in the wacom driver directory and periodically attempt to build it. When it successfully built, I stopped the X build process. Here's how to build the source for an RPM that's been exploded out into the SPECS and SOURCES directories. [root@sen root]# cd /usr/src/redhat [root@sen redhat]# rpmbuild -bc SPECS/XFree86.spec Not every distribution has /rpmbuild/; try using just /rpm/ instead. At some point, Redhat split the build functionality into separate programs. If after looking through the /rpm/ man page, you still cannot get this to work, send me some email, and I'll look into it. The important item is the "-bc" option of /rpmbuild/ which unpacks, patches, and builds the source without actually installing. While it is also possible to simply unpack and patch using the "-bp" option, there does not seem to be a way to just build. The "-bc" option simply deletes all the files provided by "-bp" and recreates them again. The downside of this is that if you wanted to simply unpack, patch, and then copy the new xf86Wacom.c file over the old one, you'll find that the build step deletes it and starts over again. I have gotten this to work by creating a new patch file, but this requires a bit more effort, so I don't recommend it right off. Step Three: Build the Original Driver The xf86Wacom.c file is buried pretty deep in the X build tree. If it is in a different location than the one I have provided below, try using /find . -name xf86Wacom.c/ from the BUILD directory. [root@sen redhat]# cd BUILD/XFree86-4.2.0/xc/programs/Xserver/hw/xfree86/input/wacom [root@sen wacom]# ls Imakefile wacom.man xf86Wacom.c.Wacom-USB-driver-a25-update Makefile xf86Wacom.c The "a25-update" file is the original xf86Wacom.c file before Redhat's patch. If you open xf86Wacom.c, you'll find that it is version 25, at least as of this writing and this distribution. The presence of the Makefile means that the configuration has at least been run for this directory. If you have built a sufficient portion of the X source files, then all the header files that you need have been generated, and you can build xf86Wacom.c. Try it, and if it does not build, wait a bit. The absence of xf86Version.h for instance, is a good indication that the build process is not ready. [root@sen wacom]# make rm -f xf86Wacom.o gcc -O2 -march=i386 ... -c xf86Wacom.c ld -r xf86Wacom.o -o wacom_drv.o Step Four: Automating the Build Process By configuring the package with the --with-xf86 option set to the XFree86 build tree, you can build the driver outside of the X build tree. [jej@ayukawa wacom]$ ./configure \ --with-xf86=/usr/src/redhat/BUILD/XFree86-4.2.0 ... BUILD ENVIRONMENT: XFree86 - yes BUILD OPTIONS: wacom_drv.o - yes [jej@ayukawa wacom]$ make The makefile rule which builds the driver is contained within src/Makefile.am and is modified according to the configuration to generate a rule similar to this in src/Makefile: xf86Wacom.o: xf86Wacom.c gcc -O2 -march=i386 -mcpu=$(ARCHITECTURE) -pipe -ansi \ -pedantic -Wall -Wpointer-arith -fno-merge-constants \ -I. -I$(XF86_DIR)/programs/Xserver/hw/xfree86/common \ -I$(XF86_DIR)/programs/Xserver/hw/xfree86/loader \ -I$(XF86_DIR)/programs/Xserver/hw/xfree86/os-support \ -I$(XF86_DIR)/programs/Xserver/include \ -I$(XF86_DIR)/programs/Xserver/mi \ -I$(XF86_DIR)/exports/include/X11 \ -I$(XF86_DIR)/include/extensions \ -I$(XF86_DIR) \ -I$(XF86_DIR)/exports/include \ -Dlinux -D__i386__ -D_POSIX_C_SOURCE=199309L -D_POSIX_SOURCE \ -D_XOPEN_SOURCE -D_BSD_SOURCE -D_SVID_SOURCE -D_GNU_SOURCE \ -DSHAPE -DXINPUT -DXKB -DLBX -DXAPPGROUP -DXCSECURITY \ -DTOGCUP -DXF86BIGFONT -DDPMSExtension -DPIXPRIV -DPANORAMIX \ -DRENDER -DGCCUSESGAS -DAVOID_GLYPHBLT -DPIXPRIV \ -DSINGLEDEPTH -DXFreeXDGA -DXvExtension -DXFree86LOADER \ -DXFree86Server -DXF86VIDMODE -DXvMCExtension \ -DSMART_SCHEDULE -DBUILDDEBUG -DXResExtension \ -DX_BYTE_ORDER=X_LITTLE_ENDIAN -DNDEBUG -DFUNCPROTO=15 \ -DNARROWPROTO -DIN_MODULE -DXFree86Module -DLINUX_INPUT \ -o xf86Wacom.o -c xf86Wacom.c similar rules applie to wcmSerial.c, wcmUSB.c, wcmISDV4.c, wcmCommon.c, wcmCompat.c, wcmConfig.c, and, wcmFilter.c. The options and directories specified come directly from the output of the make command in the previous step. All the root and parent directories have been replaced with the macro XF86_DIR which in this case is set by the configuration script to /usr/src/redhat/BUILD/XFree86-4.2.0/xc. If the options that you see in your build are identical to those above, then the default rule will work for you now. If not, you'll need to make some alterations. You can update the Makefile.am file and rerun automake, update the Makefile.in and rerun configure, or just update the Makefile directly. So long as the X build tree exists, the include directories will point to the correct locations, and the driver will build. If space is an issue, you can probably remove all the non-essential directories, but be careful; the dependency tree in X is huge. 11.2 - Building wacom_drv.o On Debian Stable The following documentation for building wacom_drv.o on Debian Stable was written by Timothy Klein. If you have any problems or questions, go ahead and post them to the list, or send email to me directly. If I cannot provide a satisfactory answer, I'll forward your email on to Timothy. Copyright (C) 2002 Timothy Klein Just thought I would give you some brief notes on compiling wacom_drv.o on Debian Stable. This must be done, as the Stable version of Debian has XFree86 v. 4.1.0.1, and your pre-compiled module is for a later version of X (4.2?). X complains about the server having ABI 2, and the module having ABI 3, and refuses to load. So one must compile the wacom_drv.o module for Debian Stable. The good news is that, while it requires a *huge* download, and takes a bit of time, it is easy. ------------------------------------------------------------- Debian wacom_drv.o Compilation *1. Download the Debian source package for XFree86.* For Debian Stable there are three files: xfree86_4.1.0-16.diff.gz xfree86_4.1.0-16.dsc xfree86_4.1.0.orig.tar.gz Note that these are *big* files. The 'diff' file is 1.5 megabytes, and the 'orig' file is 52 megabytes. So if you have a 28.8 modem connection, this is going to be painful. These files can be obtained automatically by using the command: apt-get source xfree86 It is not necessary to be root to download the source package. After it is downloaded, the package will be automatically extracted. Using this method requires that you have a valid 'source' line in your '/etc/apt/sources.list' file, though. You can also just download the three packages above from your favorite Debian mirror. If you do that, you need to extract them yourself, which is done with the following command: dpkg-source -x xfree86_4.1.0-16.dsc Either method will give you a 'xfree86-4.1.0' directory in the download directory. For both this step, and the later package creation, you are going to need tools from the 'dpkg-dev' package. So install that with 'apt-get' if you don't already have it installed. *2. Make sure you have the requisite build dependencies.* XFree86 requires certain packages to compile. It seems that 'dpkg' is pretty good about telling you what packages it needs if they are not installed (probably a nice script included by the Debian X maintainer). Thus, you can just try and compile it and see what it complains about not having and, at that point, install the needed packages with apt-get. The other, cleaner, option is to run: apt-get build-dep xfree86 This command will attempt to automatically install (or once in a blue moon uninstall) all the necessary packages to compile XFree86. You need to be 'root' to do this. *3. Begin the Build Process for xfree86* Become 'root' (or you could use fakeroot), and change into the 'xfree86-4.1.0' directory. Then run: dpkg-buildpackage The source will begin to compile. It will take a while. If you have a really old machine, like a Pentium 166 or such, go on a vacation. It may be done when you return. *4. Recompile the wacom_drv.o module.* The source you need to replace and recompile will be in the following directory: /xfree86-4.1.0/build-tree/xc/programs/Xserver/hw/xfree86/input/wacom Replace the 'xf86Wacom.c' file therein with the one provided. While X does need to have some configuration done for this to compile, and that configuration is accomplished automatically by the build process, it does not necessarily need to finish compiling the whole package. So, once a 'Makefile' is created automatically by the build scripts in this directory, you can attempt to run 'make' from time to time. Once it compiles without error, you can halt the very lengthy build process of the XFree86 package. This may not work with the current beta package since it also contains the wcm-beta.c and wcm-beta.h files. You can solve this by updating the Makefile, or proceed to step five on the Building wacom_drv.o From Scratch <#builddrv> page. The command line options for building the driver will undoubtably have changed, so be prepared to update the Makefile in the linuxwacom/src directory. *5. Move the wacom_drv.o module to the proper place.* That's it. Once the 'make' command compiles without error, you will have several new files in the directory. The one we are interested in is 'wacom_drv.o.' Now you can just move the 'wacom_drv.o' file to the directory: /usr/X11R6/lib/modules/input/ This will also require 'root' privileges. HS suggested that with debian that you should be aware of: on the next X update, the wacom_drv.o might be overwritten. So, you should use: dpkg-divert --local --rename --divert /usr/X11R6/lib/modules/input/wacom_drv.o.orig /usr/X11R6/lib/modules/input/wacom_drv.o (one line). This will move the old file aside and makes sure that it will not get overwritten on any update. But what happens when a current wacom_drv.o would get installed that would be sufficient to run the tablet? Just run: dpkg-divert --delete --rename /usr/X11R6/lib/modules/input/wacom_drv.o This should be the prefered method when files from packages get overwritten. --------------------------------------------------------------------- You may want to add that to you HOWTO, for my fellow Debian users. And thanks again for the very nice work on the HOWTO and the drivers.

I did so to insure that I got all the PPC dependency stuff right. * Hotplug kernel module issues I had some issues using 'modprobe' to load the wacom kernel module that forced me to reconfigure and rebuild the 2.4.25-ben1 kernel. A typical YDL kernel build for a PowerMac statically links most of the input core support into the kernel: [from .config file provided by YDL] # Input core support # CONFIG_INPUT=y CONFIG_INPUT_KEYBDEV=y CONFIG_INPUT_MOUSEDEV=y CONFIG_INPUT_MOUSEDEV_SCREEN_X=1024 CONFIG_INPUT_MOUSEDEV_SCREEN_Y=768 CONFIG_INPUT_JOYDEV=m CONFIG_INPUT_EVDEV=y I had initially built only wacom.o as a loadable module. The other modules were statically linked into the kernel. When wacom.o was loaded using: $ /sbin/insmod wacom.o all went well: [output from /var/log/messages] Mar 24 10:26:33 plantain kernel: usb.c: registered new driver wacom Mar 24 10:26:33 plantain kernel: Reporting max 45720, 31680 Mar 24 10:26:33 plantain kernel: wacom.c: Setting tablet report for tabletdata Mar 24 10:26:33 plantain kernel: input4: Wacom Intuos 12x18 on usb2:3.0 Mar 24 10:26:33 plantain kernel: wacom.c: v1.30-j0.6.1 Vojtech Pavlik Mar 24 10:26:33 plantain kernel: wacom.c: USB Wacom Graphire and Wacom Intuos tablet driver (LINUXWACOM-DEBUG) Mar 24 10:26:33 plantain kernel: wacom_events When wacom.o was loaded using: $ /sbin/modprobe wacom the module failed to load: $ /sbin/rmmod wacom $ /sbin/modprobe wacom modprobe: Can't locate module evdev which is needed for wacom I was perplexed about this failure because "evdev" was statically linked into the kernel. I puzzled over this for a while and concluded that it had something to do with how USB hotplug was configured. I arrived at this conclusion by unplugging the tablet, waiting, and then plugging it back in. I found that the tablet "worked" but there are complaints in /var/log/messages: Mar 24 10:34:51 plantain kernel: usb.c: USB disconnect on device 10:19.0-1 address 3 Mar 24 10:35:53 plantain kernel: hub.c: new USB device 10:19.0-1, assigned address 4 Mar 24 10:35:53 plantain kernel: Reporting max 45720, 31680 Mar 24 10:35:53 plantain kernel: wacom.c: Setting tablet report for tablet data Mar 24 10:35:53 plantain kernel: input4: Wacom Intuos 12x18 on usb2:4.0 Mar 24 10:35:53 plantain kernel: wacom_intuos_irq: tool change 0x094 Mar 24 10:35:56 plantain /etc/hotplug/usb.agent: Setup wacom for USB product 56a/24/101 Mar 24 10:35:56 plantain /etc/hotplug/usb.agent: Setup evdev mousedev for USB product 56a/24/101 Mar 24 10:35:56 plantain modprobe: modprobe: Can't locate module evdev Mar 24 10:35:56 plantain modprobe: modprobe: Can't locate module mousedev I really don't understand how the USB hotplug mechanisms are supposed to be configured. Yes... I did look at the scripts in /etc/hotplug. Yes.. I did attempt a few unsucessful modifications to usb.handmap and usb.distmap. I pondered over this for a while and then decided on a work-around: I reconfigured and rebuilt the kernel to dynamically load * evdev.o * hid.o * mousedev.o * wacom.o which "eliminated" the problem. If someone out there knows what should have been done to allow modprobe to successfully load wacom when evdev and friends are already statically linked into the kernel, please send me email. * XFree86 module: wacom_drv.o I rebuilt wacom_drv.o using the linuxwacom-0.6.1 makefile and the flags listed above. The build was uneventful. * Mouse1 I do not have a Mouse1 entry in XF86Config. I mention this because there is an obscure reference in the documentation to potential mouse conflict problems when running a USB Wacom mouse on a system with a USB mouse. The USB mouse connected to the system and the Wacom input devices all seem to work. On my system: /dev/mouse is a link to /dev/input/mice Mouse0 is configured in XF86Config as: Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "ZAxisMapping" "4 5" Option "Protocol" "IMPS/2" Option "Device" "/dev/input/mice" EndSection Maybe something nasty is going on that I don't know about. Thoughts??? * xsetwacom There are problems... The 'list' command prints stuff: $ xsetwacom list eraser eraser stylus stylus cursor cursor The set command fails: $ xsetwacom -v set stylus FileModel Set: sending 100 0 (0x0) Error (5): WacomConfigSetRawParam: Unknown X error Set: Failed to set stylus value for 'FileModel' Looking at the code, I see that it is failing in a call to XChangeDeviceControl() made from WacomConfigSetRawParam(). I also poked around in this one with GDB. The X-Display gets opened properly. Things look OK until the request is dispatched, which then returns an unknown X error. I also tried to use xsetwacom to toggle the cursor mode between relative and absolute. Again the command fails with an unkown X error. Note that the XFree86 command 'xsetmode' works fine. -Joseph 11.4 - Building wacom.ko On Debian Sid (unstable) The following documentation for building wacom kernel modules on Debian Sid was written by Steve Wallace. If you have any problems or questions, go ahead and post them to the list, or send email to me directly. If I cannot provide a satisfactory answer, I'll forward your email on to Steve. Procedure for building linuxwacom package on Debian Sid/unstable with 2.6 series kernel. These instructions are current as of June 2, 2004. I have not tested on straight Debian Sarge/testing but it should work there as well. Note that the process required to build against a 2.4 series kernel is different and not described here. Also, note that most of these steps as written require root privilege. There are better ways of doing most of this (eg. fakeroot) but I wanted to keep it simple. Some people may find that they do not need to build a new kernel at all. The wacom.c in kernel 2.6.6 seems fairly current. The changes to mousedev are needed if you want to use the /dev/input/mice device in XF86Config, otherwise events from the Wacom mouse will show up on both /dev/input/mice and /dev/input/eventN. If you use a PS/2 mouse and access it through /dev/psaux this is not needed. The changes to evdev are needed to allow the tablet to continue working correctly after being unplugged/replugged. You almost certainly do not need the usbmouse module because it conflicts with the full usb hid driver, usbhid, which should be used in most cases. If you do not wish to build a new kernel then do not enable the modules in step 6 below and skip steps 7 and 8. 1) Get development libraries needed for tools. The libncurses, tcl, tk, libgtk and libx11 development libraries are needed to build the tools. The versions shown below were current at the time of this writing. At the moment libgtk is only needed for xidump, on my system it pulled in six other development libraries so if you don't need xidump you might consider leaving out libgtk-dev. apt-get install libncurses5-dev tcl8.4-dev tk8.4-dev libgtk2.0-dev libx11-dev 2) Get kernel source and build tools. Unpack source. apt-get install kernel-package kernel-source-2.6.6 cd /usr/src tar -xjvf kernel-source-2.6.6.tar.bz2 ln -s kernel-source-2.6.6 linux cd /usr/src/linux 3) Configure kernel. I used the existing stock kernel configuration but feel free to configure your own. Using the --revision switch is suggested but not required. See /usr/share/doc/kernel-package/README.gz for more information. Note that running "make-kpkg configure" is required at this point because it creates the .../include/linux/version.h file need by linuxwacom configure. cp /boot/config-2.6.6-1-686 .config make-kpkg --revision myhost.1 configure 4) Set up links to Tcl and Tk. The naming structure expected by linuxwacom does not match Debian's unique layout. I put these links in /root but they can go anywhere. Note that this is only required to build the wacomcpl tool. Be sure to link to the library versions you actually installed in step one above. cd /root mkdir tcl cd /root/tcl ln -s /usr/include/tcl8.4 include mkdir lib cd /root/tcl/lib ln -s /usr/lib/libtcl8.4.so.0 libtcl8.4.so.0 ln -s /usr/lib/libtk8.4.so.0 libtk.so.0 5) Download the current linuxwacom package from http://linuxwacom.sourceforge.net. I used the now current 0.6.3 version. Unpack the archive somewhere convenient I chose /home/steve/wacom. cd /home/steve/wacom tar -xjvf ../linuxwacom-0.6.3.tar.bz2 cd linuxwacom-0.6.3 6) Run configure to check your system and copy the module sources into the kernel source tree. If you set up the /usr/src/linux link in step 2 above you are fine, otherwise add --with-kernel option. ./configure --with-tcl=/root/tcl --enable-wacom --enable-hid \ --enable-usbmouse --enable-evdev --enable-mousedev 7) Build your new kernel. This builds the entire kernel and all modules specified in your .config file, so it may take a while. I am using initrd here, but if you configure your own smaller kernel that is not required. cd /usr/src/linux make-kpkg --initrd --revision myhost.1 kernel_image 8) Install your new kernel. cd /usr/src dpkg -i kernel-image-2.6.6_myhost.1_i386.deb 9) Build and install linuxwacom tools. cd /home/steve/wacom/linuxwacom-0.6.3/ make make install 10) Manually install the correct wacom_drv.o for your version of X11 and kernel. cp prebuilt/wacom_drv.o_4.3k2.6 /usr/X11R6/lib/modules/input/wacom_drv.o 11) Edit your XF86Config-4 file as desribed in the linuxwacom Howto. Reboot. Enjoy. --Steve Wallace 11.5 - GNU Free Document License Version 1.2, November 2002 Copyright (C) 2000,2001,2002 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. 0. PREAMBLE The purpose of this License is to make a manual, textbook, or other functional and useful document "free" in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others. This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software. We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference. 1. APPLICABILITY AND DEFINITIONS This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The "Document", below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as "you". You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law. A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language. A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them. The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none. The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words. A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not "Transparent" is called "Opaque". Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only. The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text. A section "Entitled XYZ" means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as "Acknowledgements", "Dedications", "Endorsements", or "History".) To "Preserve the Title" of such a section when you modify the Document means that it remains a section "Entitled XYZ" according to this definition. The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License. 2. VERBATIM COPYING You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3. You may also lend copies, under the same conditions stated above, and you may publicly display copies. 3. COPYING IN QUANTITY If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects. If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages. If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public. It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document. 4. MODIFICATIONS You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version: * A. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission. * B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement. * C. State on the Title page the name of the publisher of the Modified Version, as the publisher. * D. Preserve all the copyright notices of the Document. * E. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices. * F. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below. * G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document's license notice. * H. Include an unaltered copy of this License. * I. Preserve the section Entitled "History", Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled "History" in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence. * J. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the "History" section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission. * K. For any section Entitled "Acknowledgements" or "Dedications", Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein. * L. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles. * M. Delete any section Entitled "Endorsements". Such a section may not be included in the Modified Version. * N. Do not retitle any existing section to be Entitled "Endorsements" or to conflict in title with any Invariant Section. * O. Preserve any Warranty Disclaimers. If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These titles must be distinct from any other section titles. You may add a section Entitled "Endorsements", provided it contains nothing but endorsements of your Modified Version by various parties--for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard. You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one. The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version. 5. COMBINING DOCUMENTS You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers. The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work. In the combination, you must combine any sections Entitled "History" in the various original documents, forming one section Entitled "History"; likewise combine any sections Entitled "Acknowledgements", and any sections Entitled "Dedications". You must delete all sections Entitled "Endorsements." 6. COLLECTIONS OF DOCUMENTS You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects. You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document. 7. AGGREGATION WITH INDEPENDENT WORKS A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an "aggregate" if the copyright resulting from the compilation is not used to limit the legal rights of the compilation's users beyond what the individual works permit. When the Document is included an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document. If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document's Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate. 8. TRANSLATION Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warrany Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail. If a section in the Document is Entitled "Acknowledgements", "Dedications", or "History", the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title. 9. TERMINATION You may not copy, modify, sublicense, or distribute the Document except as expressly provided for under this License. Any other attempt to copy, modify, sublicense or distribute the Document is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 10. FUTURE REVISIONS OF THIS LICENSE The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See http://www.gnu.org/copyleft/. Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License "or any later version" applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation. HOW TO USE THIS LICENSE FOR YOUR DOCUMENTS To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page: Copyright (c) YEAR YOUR NAME. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.2 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled "GNU Free Documentation License". If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the "with...Texts." line with this: with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation. If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.
