Comment 49 for bug 1007765

I can confirm the 3.6 kernel does not fix the problem, though I didn't have any of the other problems described in post #48.

Instead of the current Ubuntu 12.10 live DVD, the screen doesn't freeze, but shows the behaviour in the video previously posted. It also seemed as if a more 'agressive' change of brightness was necessary to trigger the bug (quickly increasing and decreasing the brightness).
