The bug gets ever more confusing: while logging this information, I had the expected bahavior (for the first time ever, I think). The monitor went a little darker after unplugging, and I could turn it up to maximum brightness using the hotkeys. I'll rerecord that information trying to reproduce the buggy behavior....
