Comment 6 for bug 850749

This bug affects Intel 915GM (i915) too (IBM Thinkpad X41). I have turned off 'dim'. My screen is switched off after 10 minutes. In many cases it does not turn on again completely. I can only see a very dark picture of whatever should be on the screen. I can even jump between ttys and back to the desktop with no effect. Hotkeys for brightness don't allow to increase brightness then. The only thing that helps is going to standby (closing the lid, because I can't really see where I'm clicking) and waking up, or killing the session (Alt + Print + K).
