Re: backlight problems with 180.44
In case anybody ever encounteres similar issues or nvidia intends to fix the bug:
The problem only occurs when a second display is attached and X11 is run in multihead mode. The setting is remembered over X restarts and also works in the console.
Using nvidia-settings to set Xinerama mode results in awkward "crashes" after a few minutes. I think X returns into a broken(blank) console. TwinView works fine however.
