I have a similar problem on my Dell Precision M6500. Runnign 13.04, with binary nvidia driver 331.20. It mostly seems to happen after I've turned the computer on and logged in, OR after waking from suspend. Computer will work for some undetermined length of time (a few seconds to a couple of minutes) and then the screen will go black. The computer seems to still be running, because I can see hdd activity. And when the screen goes blank, even the backlight shuts off. The computer will not repond to REISUB, and the only solution is to use the power button to power it off and back on. Sometimes, after this, it'll freeze one or two more times before becoming usable. It's done this since 12.04.

Instead I installed the nvidia- current drivers and Xorg displayed great, but now the screen often just goes black while working. This is happening when I had openSUSE installed as well as my current Ubuntu 13.04. This laptop is 3 years old and it has worked wonderfully until now. It's a Dell Precision M6500 and at first I thought it was a hardware issue, and Dell has replaced the motherboard, daughterboard, video card and hard drive, but the same issue is happening. It has taken at least 10 reboots just to get far enough to file this bug.
