Comment 37 for bug 1007765

I retested the Ubuntu 12.10 daily live version today, and unfortunately the bug does still exist in kernel 3.5. I'm not sure if I tested it wrong the first time (it seems to matter how fast you try to increase or decrease the brightness) or if this is a regression. The screen doesn't show the behaviour in the video any more though (the weird colors), now it just hangs. Switching to CLI (CTR-ALT-F1) is not possible.
