Fix mouse / touch pad issues on dell e4300

Issue, the mouse sometimes jumps when scrolling a web page or clicking on a button.

Seem to be related to the touch pad but it does help to disable the touch pad.
(enable synaptic in ubuntu https://help.ubuntu.com/community/SynapticsTouchpad)

This will fix the issue:
Edit (as root) /etc/modprobe.d/options and add:

Code:

options psmouse proto=bare

The downside is that the touch pad will stay enabled with no (?) way to disable it.
