Topic: IBM Trackpoint Scrolling under Statler (Debian Squeeze)
Had a bit of trouble getting the trackpoints middle-button scrolling working under Debian Squeeze on an x31 IBM. Followed the hal-policy directions suggested at http://wiki.debian.org/InstallingDebian Trackpoint unsuccessfully. I'm unclear as to whether this might be due to the supposed upcoming deprecation of hal (at least in ubuntu.... http://www.thinkwiki.org/wiki/How_to_co TrackPoint.)
Turns out a edit of /etc/X11/xorg.conf (you may have to create this file) and a restart of X got it working with the following code:
Section "InputClass"
Identifier "Trackpoint Wheel Emulation"
MatchProduct "TPPS/2 IBM TrackPoint|DualPoint Stick|Synaptics Inc. Composite TouchPad / TrackPoint"
MatchDevicePath "/dev/input/event*"
Option "EmulateWheel" "true"
Option "EmulateWheelButton" "2"
Option "Emulate3Buttons" "false"
Option "XAxisMapping" "6 7"
Option "YAxisMapping" "4 5"
