One day ago I booted up my laptop – which was fine when I shut it down the day before – and all of a sudden every time I touch the touch-pad my screen flickers a few times and and I'm back at the log-in screen. It took me a while to figure out it was my touch-pad. It seemed random at first. I tried my mouse, my Wacom tablet and Alt-space > m all made X server crash.

I have no idea where to look. All I know is that I would love to have this fixed because navigating keys only starts to become a pain.

As requested last part of my Xorg.0.log:

I just downgraded xserver and it worked:

sudo apt-get install xserver-xorg-core=2:1.10.4-1ubuntu4
