Getting Trackpoint scrolling working on a Lenovo X301 in Ubuntu 10.04 (Lucid)
Further to my previous post on this subject detailing how to get this to work on Ubuntu Karmic (9.10), here are details for getting it working in Lucid (10.04).
If you followed the previous instructions, you will want to remove the file created there:
rm /etc/hal/fdi/policy/thinkpad.fdi
Create the file /usr/lib/X11/xorg.conf.d/20-thinkpad.conf as root with the following content:
Section "InputClass"
Identifier "Trackpoint Wheel Emulation"
MatchProduct "TPPS/2 IBM TrackPoint|DualPoint Stick|Synaptics Inc. Composite TouchPad / TrackPoint|ThinkPad USB Keyboard with TrackPoint"
MatchDevicePath "/dev/input/event*"
Option "EmulateWheel" "true"
Option "EmulateWheelButton" "2"
Option "Emulate3Buttons" "false"
Option "XAxisMapping" "6 7"
Option "YAxisMapping" "4 5"
EndSection
Restart X/Ubuntu and test!
