After I woke my mac from sleep, I noticed that the laptop screen (I am using a Dell 2005FPW as my primary) has changed back to Adobe RGB profile all by itself. Totally magic. When I try to change it back to anything else, the 'dung' sound pops up and it won't register the change. Fun. A relogin fixes it, but it has done this twice by itself and it's bugging the crap out of me. Is there some sort of .plist I can delete to revert it back to default?
