My mother has a problem with her ThinkPad L520 notebook (Ubuntu 11.10, Unity).
She boots the device, everything works fine at first. But then, out of nowhere, her touchpad + trackpoint stop working. She can't click or drag the mouse. If she connects an external mouse, she can move the pointer and click (but the internal touchpad or trackpoint still don't work).
She already updated everything through the update manager, but still no I said, sometimes it works, sometimes it doesn't.
There are no 'special' mouse drivers installed.
What can I do to fix this?

Thank you for your help! :)

okay, I continued to search for a solution, another person told me to type 'unity --replace' into my terminal. unfortunately the problem still persists. any other recommendations? – yesyoar Apr 11 '12 at 13:32

I had the exact same problem/config, typing

synclient TouchpadOff=0

in a terminal solved it.
