I believe I have similar problem with my laptop, a LG LW65 Express. I am using Ubuntu 10.04 and it works fine, but sometimes the screen goes black and the system simply doesn't respond, requiring a so called hard reset. My VGA card is an ATI x700 mobility. In my opinion, the crashes are completely random. They don't happen because I start an extremely demanding application, they come out of nowhere.
