Comment 28 for bug 1258837

I have been following this thread over the past couple of weeks and tried several things, including what's outlined in comment #5.

I found that running:

modprobe -r psmouse
modprobe psmouse proto=bare

solves the issue for me. However the caveat is that you don't have access to advanced touchpad features like scrolling.

The other effect of the above is that both track point and touchpad are active. I only use the track point. Since I constantly brush against the touchpad, I am still looking for a way to disable this. With the settings above, I can no longer disable the touchpad via "System Settings..." > "Mouse and Touchpad". So, if anyone knows how to do that....

Oh, to make the above changes permanent, create a file called "/etc/modprobe.d/47440-mouse.conf" with the content:

options psmouse proto=bare

I hope this helps someone.
