Howdy, I've downloaded latencytop (0.5-10.1), and when I run it, my video goes blank. My kernel is This system is an Intel Atom D410PT. I have reloaded latencytop with no improvement. I've also tried to set the screen resolution to 800 by 600 (it was 1280 by 1024) and the same thing happens.
Sometimes the loss of video is immediate; sometimes it "works" for 15 seconds then the screen goes blank. I'm hesitant to call this a failure, since it's loss of view... I really don't know the state of the system.

I'd appreciate any help!
