When using Ubuntu 12.04, if I happen to touch one of the extreme edges of my touchpad, my cursor spontaneously jumps to the top left corner of the screen. I have tried disabling all touchpad features within system settings, but this behavior persists.

Is this a bug or a "feature" gone wrong? Can anybody help me out? Thanks.

Similar behaviour here - except it jumps to the bottom left sporadically, almost always when I am about to use my left hand to left-click at the bottom left of the touchpad, and my right hand is elsewhere near (i.e. just touching on or above) the touchpad. See askubuntu.com/questions/792098/… . – Steve Kroon Jul 7 at 8:01

It seems to be some problem in your touchpad drivers. Try the following command:

sudo apt-get install --reinstall xserver-xorg-input-synaptics

Do you experience the same when booted from the Live USB or CD? – green Aug 19 '12 at 13:04

Interestingly, no. – Tom D Aug 20 '12 at 14:44
