These are specific insturctions on how to get your Wacom Graphire Bluetooth working in Ubuntu. Please help to keep this page updated!

Ubuntu 8.04 "Hardy"

WARNING: This is not entirely simple and involves using the linux terminal, editing system files and compiling a kernel module. Even so, it should be pretty straightforward if you follow the steps.

1. Pairing the tablet with your computer

• press the connect button on the tablet (turn the tablet upside down - it should be near the top right corner)
• From the main Ubuntu menu, select System > Preferences > Bluetooth, then select the Services tab.
• Click on Input Service, select the wacom tablet (which should appear in the bottom pane) and click add.

2. Compiling the new hidp kernel module

NOTE: This step needs to be repeated EVERY TIME your kernel version changes. To compile a kernel module you will need to have basic build tools and the linux kernel headers installed. First find out which kernel version you are using by opening a terminal (Accessories > Terminal) and typing:

user@computer:~$ uname -r
2.6.24-16-generic
user@computer:~$ 

Using the suffix here (in this case, "generic"), install the relevant linux-headers package. In my case, my kernel version is 2.6.24-16-generic, so the linux-headers package I want is linux-headers-generic. Also install the build-essential package, as this should install all the utilities you need to compile the module.

user@computer:~$ sudo apt-get install linux-headers-generic build-essential

Download the module source from [1] then extract it somewhere (e.g. your desktop). In the terminal, switch to the folder that was created and compile the module by typing “make”.

user@computer:~$ cd Desktop/wacom-bt-driver
user@computer:~/Desktop/wacom-bt-driver$ make

This should not show any errors, and you should now have a file “hidp.ko” in the hidp subfolder.

user@computer:~/Desktop/wacom-bt-driver$ ls hidp/hidp.ko
hidp/hidp.ko
user@computer:~/Desktop/wacom-bt-driver$ 

Now to install this module, first make sure your tablet is turned off, then type:

user@computer:~/Desktop/wacom-bt-driver$ sudo make install

When it asks for your password, just type it in and hit enter.

3. Get the tablet working in X

To make sure the proper event symlinks are created, you need to edit the wacom udev rules.

user@computer:~$ sudo gedit /etc/udev/rules.d/50-xserver-xorg-input-wacom.rules

Find the lines:

# Convenience link for the common case of a single tablet.

KERNEL=="event[0-9]*", SYSFS{idVendor}=="056a", SYMLINK="input/wacom"

and add a slightly modified line below:

# Convenience link for the common case of a single tablet.

KERNEL=="event[0-9]*", SYSFS{idVendor}=="056a", SYMLINK="input/wacom"
KERNEL=="event[0-9]*", SYSFS{id/vendor}=="056a", SYMLINK="input/wacom"

Similarly, modify the end of the file as such, also adding a specific link for the graphire bluetooth.

# Bluetooth tablets
KERNEL=="event[0-9]*", SYSFS{id/vendor}=="056a", SYSFS{id/product}=="0081", SYMLINK+="input/tablet-graphire_bt-6x8a"

# Check and repossess the device if a module other than the wacom one
# is already bound to it.

KERNEL=="event[0-9]*", SYSFS{idVendor}=="056a", ACTION=="add", RUN+="/lib/udev/check_driver wacom $devpath $env{ID_BUS}"
KERNEL=="event[0-9]*", SYSFS{id/vendor}=="056a", ACTION=="add", RUN+="/lib/udev/check_driver wacom $devpath $env{ID_BUS}"

This should ensure that the symlinks /dev/input/wacom and /dev/input/tablet-graphire_bt-6x8a point to your tablet. Now edit your Xorg configuration to enable the tablet.

user@computer:~$ gksudo gedit /etc/X11/xorg.conf

Find the lines relating to wacom tablets and modify them so that they read as follows:

Section "InputDevice"
	Driver		"wacom"
	Identifier	"stylus"
	Option		"Device"	"/dev/input/wacom"
	Option		"Type"	"stylus"
	Option		"Mode"  "absolute"
EndSection

Section "InputDevice"
	Driver		"wacom"
	Identifier	"eraser"
	Option		"Device"	"/dev/input/wacom"
	Option		"Type"	"eraser"
	Option		"Mode"  "absolute"
EndSection

Section "InputDevice"
	Driver		"wacom"
	Identifier	"cursor"
	Option		"Device"	"/dev/input/wacom"
	Option		"Type"	"cursor"
	Option		"Speed"  "3.0"
	Option		"Mode"  "relative"
EndSection

The "Speed" option in the "cursor" section can be tweaked to match the sensitivity of the mouse on the tablet with any other controllers you use. I've found 3.0 to work well for me. To slow the cursor down, you can use speed values of less than 1.0, e.g. a value of 0.5 would make the tablet mouse cursor twice as slow as a value of 1.0. To get the buttons on the tablet working, add a similar section underneath them called "pad":

Section "InputDevice"
	Driver		"wacom"
	Identifier	"pad"
	Option		"Device"	"/dev/input/wacom"
	Option		"Type"	"pad"
EndSection

Also uncomment the “InputDevice” lines in the ”ServerLayout” section, and add a line for the "pad".

Section "ServerLayout"
	Identifier	"Default Layout"
	Screen		"Default Screen"
	Inputdevice	"Generic Keyboard"
	Inputdevice	"Configured Mouse"
	
	# Uncomment if you have a wacom tablet
	InputDevice     "stylus"	"SendCoreEvents"
	InputDevice     "cursor"	"SendCoreEvents"
	InputDevice     "eraser"	"SendCoreEvents"
	InputDevice	"pad"
EndSection

Save your work and restart X by logging out and then back in again, or by pressing ctrl-alt-backspace. You should now have a fully working graphire bluetooth tablet!

Final Notes

Please remember that when your kernel version gets upgraded (which is usually the only time your computer will recommend a restart after updating) you need to do step 2 again. If you saved the driver source, all you need to do is restart into the new kernel, then do the "make", "sudo make install" bit again. Also note that when you turn the tablet on, it may function incorrectly. To solve this, press CTRL-ALT-F6 to switch to another virtual terminal, and CTRL-ALT-F7 to switch back to X. Also, You must have your tablet turned on when you log in. So if switching terminals and back hasn't worked, save your work, log out, and log back in again. This limitation also exists for USB Wacom tablets, but they are usually plugged in all the time. useful links:
