dodgy trackpoint on dell latitude c600

My C600’s trackpoint mouse has a tendency to cause the mouse cursor to drift annoyingly at random. I’ll bump it and the cursor will be stuck in the bottom left corner for 5 minutes, or I’ll hit G, H or B on the keyboard and it’ll freak out and run away, it has happened completely at random. I think it’s a common problem; mine does it, and so did one that came into work the other week.

The obvious fix is to turn the trackpoint off (who the hell uses them anyway?). To do that, you need the proper touchpad drivers – get them from Dell here (Dell’s generic driver download page is here, if you have a different model).

Thing is, the driver application only runs per-user once you’ve logged in. The trackpoint can still play havoc at the login screen, especially if you use the Welcome screen. To fix that, just set SynTPLpr.exe to run as a scheduled task on system startup:

Just remember to untick all the stupid defaults so it runs even if you’re on batteries (and thus probably particularly reliant on the touchpad):

    Same problem on a Compaq Evo N610c. All I have to do is use the trackpoint to move the cursor from one side of the screen to the other, and that’s enough to send it way out of calibration.

    Unfortunately for me, there’s not an easy control panel for turning it off in Ubuntu that I know of. I know I could do it in Windows, but I scrapped that ages ago.
