TrackPoint scrolling in Ubuntu 10.10

I just upgraded to Ubuntu 10.10 on my ThinkPad and the only issue so far is that TrackPoint scrolling had stopped working. To re-enable it I used GPointingDeviceSettings and set the following settings:

The important change was to set the wheel emulation’s button to 2, not 4 as it appeared to have been set to. If you don’t have GPointingDeviceSettings installed:

sudo apt-get install gpointing-device-settings

Update:

This original method didn’t survive a power-cycle but I found adding this file to /usr/share/X11/xorg.conf.d/20-thinkpad.conf will work:

Section "InputClass"
    Identifier "Trackpoint Wheel Emulation"
    MatchProduct "TrackPoint"
    MatchDevicePath "/dev/input/event*"
    Driver "evdev"
    Option "EmulateWheel" "true"
    Option "EmulateWheelButton" "2"
    Option "Emulate3Buttons" "false"
    Option "XAxisMapping" "6 7"
    Option "YAxisMapping" "4 5"
EndSection
