I cannot say for sure if hibernating is necessary to trigger the problem or not... every time I've seen the problem, it's been after using hibernate-ram a couple of times, but I also haven't left the laptop running continuously for a couple of days before. I usually carry my laptop with me during the day, so it's not really practical to leave it on continuously. It definitely doesn't happen immediately after resuming from suspend, though. I can resume from suspend, watch some YouTube videos with no problem, and have the problem pop up a couple of hours later. This bug is the only issue preventing me from switching exclusively to linux, so I really hope to find a fix for it -- I just don't know where to start. (I also hope for the ability to independently load separate color profiles for each monitor using xcalib, but that's minor) Chun-Yu
