how to configure a trackpoint only mode on thinkpads with clickpads
Solution 1:
The Option "Synaptics Area" "0 0 0 1" does not work properly. Hence all that is needed is:
Section "InputClass"
Identifier "tp only with clickpad buttons"
MatchDriver "synaptics"
Option "SoftButtonAreas" "60% 0 0 0 40% 60% 0 0" #Emulate right and midle buttons
Option "AreaBottomEdge" "1" #disable moving but not buttons
EndSection
store this in a file 99-carbonx1clickpad.conf in the folder /usr/share/X11/xorg.conf.d/
