Sabayon: touchscreen tutorial.
Finally, the Sabayon Wacom (touch, stylus, eraser) tutorial.
First of all, Sabayon already have wacom kernel module included and wacom tools in repository so, i will split the tutorial in a few parts:
1. Using included driver.
2. Compile from source.
3. Configure X server.
4. OnScreen keyboard.
As i said, Sabayon already have the kernel module included. Unfortunately it didn’t work for me but maybe you are lucky 
Load the kernel module and check if touch and stylus are detected. If you get an error you are unlucky… just like me so, you have to compile it from source (step 2):
catalin@atlantis ~ $ sudo modprobe wacom catalin@atlantis ~ $ dmesg | grep -i wacom [ 23.392334] wacom: probe of 7-2:1.0 failed with error -113 [ 23.395185] input: Wacom ISDv4 93 as /class/input/input10 [ 23.404521] usbcore: registered new interface driver wacom [ 23.404532] wacom: v1.49:USB Wacom Graphire and Wacom Intuos tablet driver catalin@atlantis ~ $
If everything is ok and you you have to check if wacom tools are installed:
catalin@atlantis ~ $ sudo modprobe wacom catalin@atlantis ~ $ dmesg | grep -i wacom [ 23.355233] input: Wacom ISDv4 93 as /class/input/input10 [ 23.377350] input: Wacom ISDv4 93 as /class/input/input11 [ 23.388137] usbcore: registered new interface driver wacom [ 23.388137] wacom: v1.49:USB Wacom Graphire and Wacom Intuos tablet driver catalin@atlantis ~ $

If is not installed then use equo to install it
catalin@atlantis ~ $ sudo equo install linuxwacom
Load wacom module at startup:
catalin@atlantis ~ $ sudo echo "/sbin/modprobe wacom" >> /etc/conf.d/local.start catalin@atlantis ~ $ sudo chmod +x /etc/conf.d/local.start
Reboot.
Go to step 3 to configure X.
First, download the latest version of linuxwacom from http://linuxwacom.sourceforge.net/
In this moment, 0.8.2-2 is the last version and it supports kernels up to 2.6.28.
catalin@atlantis ~ $ mkdir wacom catalin@atlantis ~ $ cd wacom catalin@atlantis ~/wacom $ wget http://prdownloads.sourceforge.net/linuxwacom/linuxwacom-0.8.2-2.tar.bz2 catalin@atlantis ~/wacom $ tar -xjf linuxwacom-0.8.2-2.tar.bz2 catalin@atlantis ~/wacom $ cd linuxwacom-0.8.2-2 catalin@atlantis ~/wacom/linuxwacom-0.8.2-2 $ ./configure --prefix=/usr --enable-wacom catalin@atlantis ~/wacom/linuxwacom-0.8.2-2 $ make catalin@atlantis ~/wacom/linuxwacom-0.8.2-2 $ sudo make install
Now, backup the included kernel module and copy the new one:
catalin@atlantis ~/wacom/linuxwacom-0.8.2-2 $ sudo cp /lib/modules/`uname -r`/kernel/drivers/input/tablet/wacom.ko /lib/modules/`uname -r`/kernel/drivers/input/tablet/wacom.ko.included catalin@atlantis ~/wacom/linuxwacom-0.8.2-2 $ sudo cp src/2.6.27/wacom.ko /lib/modules/`uname -r`/kernel/drivers/input/tablet/wacom.ko catalin@atlantis ~/wacom/linuxwacom-0.8.2-2 $ sudo depmod -a
Load wacom driver at startup:
catalin@atlantis ~ $ sudo echo "/sbin/modprobe wacom" >> /etc/conf.d/local.start catalin@atlantis ~ $ sudo chmod +x /etc/conf.d/local.start
Reboot.
After reboot, check if the touchscreen and stylus were correctly detected:
catalin@atlantis ~ $ dmesg | grep -i wacom [ 23.355233] input: Wacom ISDv4 93 as /class/input/input10 [ 23.377350] input: Wacom ISDv4 93 as /class/input/input11 [ 23.388137] usbcore: registered new interface driver wacom [ 23.388137] wacom: v1.49:USB Wacom Graphire and Wacom Intuos tablet driver catalin@atlantis ~ $
If you get an error again (touch or stylus not detected), i’m sorry, i can’t help you anymore.
For any other problems (download, compiling, installing, etc), post a comment here.
If everything is ok, go to next step, configure X server.
First step, backup your xorg.conf file and .xinitrc:
catalin@atlantis ~ $ sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.working catalin@atlantis ~ $ cp .xinitrc .xinitrc.working
Remove any “xsetwacom” settings from your .xinitrc and any old experiments for touch, stylus, eraser from xorg.conf file.
If you have any entries named “Touchpad” in your xorg.conf (i have: Identifier “Synaptics Touchad” and InputDevice “Synaptics Touchpad”) rename them to “Pad“. In my case: Identifier “Synaptics Pad” and InputDevice “Synaptics Pad”.
Open (using sudo) /etc/X11/xorg.conf in your preferred editor and add next lines to: Section “ServerLayout”:
Inputdevice "stylus" "SendCoreEvents" Inputdevice "touch" "SendCoreEvents" Inputdevice "eraser" "SendCoreEvents"
Add next lines above Section “Screen”:
Section "InputDevice" Identifier "stylus" Driver "wacom" Option "Type" "stylus" Option "USB" "on" Option "Device" "/dev/input/by-path/pci-0000:00:14.5-usb-0:2:1.0-wacom" Option "Button2" "3" # make side-switch a right button Option "TopX" "225" Option "TopY" "225" Option "BottomX" "26300" Option "BottomY" "16375" EndSection Section "InputDevice" Identifier "eraser" Driver "wacom" Option "Type" "eraser" Option "Device" "/dev/input/by-path/pci-0000:00:14.5-usb-0:2:1.0-wacom" Option "USB" "on" EndSection Section "InputDevice" Identifier "touch" Driver "wacom" Option "Type" "touch" Option "USB" "on" Option "Device" "/dev/input/by-path/pci-0000:00:14.5-usb-0:2:1.1-wacom" Option "TopX" "200" Option "TopY" "225" Option "BottomX" "4000" Option "BottomY" "3875" EndSection
Now, run the following commands:
catalin@atlantis ~ $ dmesg | grep -i wacom [ 23.355233] input: Wacom ISDv4 93 as /class/input/input10 [ 23.377350] input: Wacom ISDv4 93 as /class/input/input11 [ 23.388137] usbcore: registered new interface driver wacom [ 23.388137] wacom: v1.49:USB Wacom Graphire and Wacom Intuos tablet driver
catalin@atlantis ~ $ ls -al /dev/input/by-path/ total 0 drwxr-xr-x 2 root root 240 2009-02-07 12:37 . drwxr-xr-x 4 root root 420 2009-02-07 12:37 .. lrwxrwxrwx 1 root root 9 2009-02-07 12:36 pci-0000:00:13.2-usb-0:2:1.0-event- -> ../event9 lrwxrwxrwx 1 root root 10 2009-02-07 12:36 pci-0000:00:14.5-usb-0:2:1.0-event-mouse -> ../event10 lrwxrwxrwx 1 root root 9 2009-02-07 12:36 pci-0000:00:14.5-usb-0:2:1.0-mouse -> ../mouse2 lrwxrwxrwx 1 root root 10 2009-02-07 12:36 pci-0000:00:14.5-usb-0:2:1.0-wacom -> ../event10 lrwxrwxrwx 1 root root 9 2009-02-07 12:36 pci-0000:00:14.5-usb-0:2:1.1- -> ../mouse3 lrwxrwxrwx 1 root root 10 2009-02-07 12:36 pci-0000:00:14.5-usb-0:2:1.1-event- -> ../event11 lrwxrwxrwx 1 root root 10 2009-02-07 12:36 pci-0000:00:14.5-usb-0:2:1.1-wacom -> ../event11 lrwxrwxrwx 1 root root 9 2009-02-07 12:36 platform-i8042-serio-0-event-kbd -> ../event5 lrwxrwxrwx 1 root root 9 2009-02-07 12:36 platform-i8042-serio-1-event-mouse -> ../event6 lrwxrwxrwx 1 root root 9 2009-02-07 12:36 platform-i8042-serio-1-mouse -> ../mouse1 catalin@atlantis ~ $
You have in “dmesg” output something like:
/class/input/input10 and /class/input/input11
The important part is input10 and input11.
Find in “ls -al” output the input devices pointing to event10 and event11 (in your case 10 and 11 may be different but you got the idea).
We have here pci-0000:00:14.5-usb-0:2:1.0-wacom for event10 and pci-0000:00:14.5-usb-0:2:1.1-wacom for event11.
Modify the Option “Device” for stylus and eraser to point to the device identified for event10 (in my case: /dev/input/by-path/pci-0000:00:14.5-usb-0:2:1.0-wacom) and the Option “Device” for touch to point to the device identified for event11 (in my case: /dev/input/by-path/pci-0000:00:14.5-usb-0:2:1.1-wacom)
Save the file, close all applications and restart X server (Ctrl + Alt + Backspace).
My xorg.conf is available for download here.
If you don’t like the default calibration, use wacomcpl to calibrate:
catalin@atlantis ~ $ wacomcpl
After make your .xinitrc executable:
catalin@atlantis ~ $ chmod +x .xinitrc
And go to System->Preferences->Session (if you use Gnome… for KDE is probably different), click on Add and write in the command field: ~/.xinitrc
The calibration will be only for the current user.
If you want them system wide, use the values in .xinitrc to set TopX, TopY, BottomX, BottomY in xorg.conf
I use cellwriter but is not included by default in Sabayon. Use equo to install it:
catalin@atlantis ~ $ sudo equo install cellwriter
After go to System->Preferences->Session click on Add and write in the command field: cellwriter –hide-window –window-y=600 –keyboard-only
To login using OnScreen keyboard in tablet mode, you need two things:
a) add cellwriter –window-y=600 –keyboard-only –read-only & to /etc/X11/gdm/Init/Default before “exit 0″
b) forget about fancy login themes
catalin@atlantis ~ $ sudo gdmsetup
Go to “Local” tab, select Style: “Plain with face browser” and Close.
I personally don’t use it due to security reasons…
Anyway, if you know how to use the OnScreen keyboard WITH login themes, let me know please.
If you have comments, questions, know tools to make all the job easier, etc. just leave me a comment here and i’ll answer.

Hi,
thank you for this useful tutorial.
Maybe you want to use the device nodes in /dev/input/by-id/ instead of /dev/input/by-path/ because the path may change if you connect the tablet do another USB connector.

Hm i followed this guide and I was with this a little bit more succesfull.
Following this guide my second button of the pen works (context menu will popup), but if i touch the screen with the pen, it blinks down to right corner of the screen and i cant get it working properly.
I suppose it has something to do with Xorg.conf,
im using Siemens Fujitsu T4215 tablet / newest sabayon.
But i dont get input10&11..

Okay resolved this, my problem was that input10/11 was named like that.
My case it was:
/path/to/
platform-i8042-serio-4-event-mouse
platform-i8042-serio-0-event-kbd
platform-i8042-serio-4-mouse
event-mouse >> eraser (or touch)
event-kbd >> touch (eraser)
mouse >> stylus (always)
