I own an old Dell Inspiron 4000 laptop whose trackstick / trackpoint (the blue little joystick in the middle of the keyboard) has become really annoying : typing on the keyboard, or even touching the surface of the laptop generate parasite movements of the pointer.
I've looked for a way to disable it, and found one way using
hal (since X is auto-configured in Ubuntu now), by adding the following file as
<?xml version="1.0" encoding="UTF-8"?> <deviceinfo version="0.2"> <device> <match key="info.product" contains="TPPS/2 IBM TrackPoint"> <remove key="input.x11_driver"/> </match> </device> </deviceinfo>
Thanks to this post by Brice Goglin for he hint on how to disable a device.
