greets!
I was trying to get a second monitor (a tv) to work using xrandr. I noticed that the screen on the laptop would suffer severe, almost 'psychedelic', effects if I hit a certain setting.
unfortunately I don't recall the setting but the ill effect was consistent and rendered the disply nearly unreadable. and the only solution was to end the session.
then by accident I hit the 'save this configuration' key and now the setting is permanent.
btw I created a second user and it doesn't suffer from the problem.
I cannot find a way to restore the proper display setting.
My guess is that you did something awkward to the color profile or gamma correction. No idea where that information is stored, though--I'd probably resort to grepping through likely directories looking for "[Cc]olor". If it affects only a specific user, then the setting is probably in your home directory, since most distros don't like mingling user settings with general system settings.
