I have a Thinkpad T431s with trackpoint (the red stick in the middle of the keyboard) and clickpad (a touchpad that also acts as a button). This is the first model that does not provide any dedicated buttons for the trackpoint. I want to use the trackpoint only. So far I'm able to configure the clickpad such that it acts as buttons for the trackpoint while disabling motion via:
# Devide the clickpad into 3 areas for left/middle/right click xinput set-prop 10 "Synaptics Soft Button Areas" 3477, 5112, 0, 0, 2659, 3476, 0, 0 # Disable mouse movements xinput set-prop 10 "Device Accel Constant Deceleration" 9999999 # Disable tap events xinput set-prop 10 "Synaptics Tap Action" 0, 0, 0, 0, 0, 0, 0
where 10 is the ID of the clickpad.
However, I can't figure out how to configure the trackpoint to use the middle button for scroll emulation. The problem seems to be that the trackpoint device does not have any real buttons. Thus the following does not work:
xinput set-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation" 1 xinput set-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation Button" 2
Is there any way configure the trackpoint to use the middle button of another device (the clickpad) for scroll emulation? Any other suggestions?
