Hi sanette, Favux
my father would like to say: Someone who can read is in advantage.
That is what i have done to get my buttons work.
1.) read reply #89 from Favux again 
2.) read Section 3: Calibrating your Tablet PC.
2.1) Call This creates .xinitrc in my home directory
2.2) Important! Edit xinitrc in /etc/X11/xinit. Look for
Code:
# invoke global X session script
. /etc/X11/Xsession
comment out the last entry like this:
Code:
# invoke global X session script
#. /etc/X11/Xsession
this prevent a loop in the startup script
2.3) make .xinitrc executable
Code:
chmod +x ~/.xinitrc
2.4) add the following entry in System->Preferences->Startup Applications. Change <username> to your name.
Code:
sh /home/<username>/.xinitrc
3.) read the posting #188 http://ubuntuforums.org/showthread.php?t=967147&page=19
3.1) For interest is the code section
Code:
xsetwacom set pad Button4 "core key NumpadMinus "
xsetwacom set pad Button3 "core key NumpadPlus "
xsetwacom set pad Button2 "core key F12 "
xsetwacom set pad Button1 "core key Esc"
3.2) I insert manually in a terminal
Code:
xsetwacom set pad AbsWDn "+ "
xsetwacom set pad AbsWUp "- "
3.3) The touchring should insert '+' or '-' in the terminal
3.4) Now i edit the .xinitrc in my home directory and I insert
somthing stupid like key 'A' up to Key 'I'
Code:
#buttons on the left side of the tablet
xsetwacom set pad Button1 "core key A " #button inside touchring
xsetwacom set pad Button2 "core key B " #top button
xsetwacom set pad Button3 "core key C "
xsetwacom set pad Button4 "core key D "
xsetwacom set pad Button5 "core key E "
xsetwacom set pad Button6 "core key F "
xsetwacom set pad Button7 "core key G "
xsetwacom set pad Button8 "core key H "
xsetwacom set pad Button9 "core key I " #bottom button
3.5) save and restart
3.6) start an editor and you can write with the buttons ABCDEFGHI. Great!
Thanks for all your help,
