I'm experencing a consistent problem where my laptop display appears to lose sync with the controller. I'm not certain of the correct terminology but the details from the screen appear to be there (say, if I have a gnome-terminal open [with black text, white background] and hold down Ctrl-C, a set of vertical black lines appears). The colours are unaffected, just the content is scrambled, with defined edges. The problem appears randomly, sometimes it will happen after a few seconds, other times it will go for hours with no problems. I also experience the intermittent flicker (very short flashes of black) reported by other users.
I'm running Gnome with compiz as window manager.
When I suspend to RAM the problem is gone on restart (if it restarts - but that's probably another issue), but using Ctrl-Alt-FnPlus/FnMinus to swicth resolutions has no effect. I can see the screen content changing as I switch through the modes but they're all scrambled in the same way.
