Hi, I have the same erratic behaviour Dell Lat E6510 Ubuntu 11.10. The
trackpad is cool. The external mouse is cool. Pressing on the palmrest
(a test asked for by Dell service center) has no effect. Dell replaced
the palmrest assembly containing the trackpad last week. The problem
disappeared for a few days and yesterday it came back.
As I run Linux, dell asked me to go to the BIOS config screen (boot+F2)
and try the external mouse, trackpad and touch pad. Mounse was cool,
trackpad was cool, touchpad same erratic behaviour. I hope this absolves
Linux. UNLESS the Linux driver is collecting some adaptive calibration
information in real time and programming derived numbers back into some
touchpad hardware calibration register. I have no idea if this is ever
done, Its just a thought.
Good luck guys. Hope this helps
Justin
