Sometimes, when the computer screen goes off, my laptop will flash the screen on black for a second, give me a cursor for less time that, and then go off. It then repeats this indefinitely. When I was installing via the live CD, it did the same thing, but it did not while I was installing without the live CD. This may because I moved the mouse more, or it took less time. Anyways, I am pasting my specs below. I have had this problem with both the open source driver, and the latest driver from NVIDIA. I have similar issues when waking from sleep.
