In Cinnamon, the GUI for Wacom tablet offer minimal yet powerful set
of options: set buttons, set proportions to the screen...etc... The
GUI is limited because you can't assign buttons modifier like ,
and ...
Xsetwacom: For those who really need a way to assign this key and do more, here is the (big) workaround involving command line,
script and other dirty things a normal user shoudn't consider as
something normal to setup an hardware (graphist needs a GUI and focus
on making good graphism, not script/code):
1. Get your tablet device name:
xsetwacom --list
This command returns the name of my Wacom device, useful for my
script:
Wacom Intuos3 9x12 Pen stylus id: 11 type: STYLUS
Wacom Intuos3 9x12 Pad pad id: 12 type: PAD
Wacom Intuos3 9x12 Pen eraser id: 15 type: ERASER
Wacom Intuos3 9x12 Pen cursor id: 16 type: CURSOR
Note for reference your tablet pad name, mine here is Wacom Intuos3
9x12 Pad pad in this example. Select the name, then press
++C to copy it in your terminal.
2. Create a Xsetwacom bash script Open the file manager (Nemo) , and in the folder of your choice ( I use /home/deevad/Script on my
installation ) create a new empty file with right-click , "create a
new document">"Empty document". Name it tablet.sh , then open it with
a text-editor (Gedit). Inside it write a script like this with your
tablet name:
#! /bin/bash
xsetwacom set "Wacom Intuos3 9x12 Pad pad" Button 1 "key Shift_L"
xsetwacom set "Wacom Intuos3 9x12 Pad pad" Button 2 "key Control_L"
This example script will map to the button 1 of your tablet
(resize brush in Krita) , and Control to the button 2 ( pick color on
Krita/Gimp/Mypaint) of the tablet. The special keys use standard
names, for assigning other type of key I paste here a list :

If you want to assign a modifier ( eg. Ctrl ) on the stylus button,
it's also possible:
xsetwacom set "Wacom Intuos3 9x12 Pen stylus" Button 2 "key ctrl"
You can test all your xsetwacom lines inside the Terminal before
writing them in your script. This way you'll test if you have a Button
5 , or Button 20... etc... For my Intuos 3, the layout of the
right side is like this ( I found it with guessing and trying ):
# ---------
# | | 1 |
# | 3 |---|
# | | 2 |
# |-------|
# | 8 |
# ---------
When your script is finished you can save it. In the file-manager ;
right-click on it again > Properties > Permissions > and in front of
Execute check the box for 'Allow executing file as a program'.
3. Run it, create a start-up You can double click and run the script. Your key on tablet will be mapped. But all setup of the button
will not last a reboot. That's why we made a script to execute it at
each start-up. Go now on 'System Settings', then 'Start-up
application' , press the 'Add' button , give the form a name of your
choice, for the command pick your script via the 'Browse' button, and
comment what you want about it.
