Comment 6 for bug 1531167

It also happens to me. Not only the screen got crazy, the system restarted it self like is told in this bug:

The screen went definitely idle and the system restarted it self. The first thing I could see was the ubuntu init splash I said it because I don't know if it could be related.

If you got any question...
