In the newer Ubuntu's they've moved to evdev, which is a much more dynamic system for configuring input devices. Unfortunately, it doesn't quite seem to understand that I want wheel emulation on my Thinkpad's trackpoint. Fortunately, there seems to be a way to set it explicity. I use the following script:
#!/bin/sh DEVICEID=3 xinput set-int-prop $DEVICEID "Wheel Emulation" 8 1 xinput set-int-prop $DEVICEID "Wheel Emulation Button" 8 2 xinput list-props $DEVICEIDThe value for DEVICEID can be figured out by running the command
xinput list and looking for entry. On mine there's a line that says:
"TPPS/2 IBM TrackPoint" id=3 [XExtensionPointer]
Looks like the settings get reset when you come back from resume, so you have to run the script again. I'm sure there's some way to do it automatically, but I frankly haven't run Linux enough on this laptop to be bothered to figure that part out.
