Hi, I think the problem may be due to overheating. I've added an additional fan pointing directly at the graphics card and made sure my computer has space to vent heat, and I've not had any problems since. I did this around 7 hours ago and the computer has been running since, letting me play games and stream video at the same time on multiple monitors.
Before doing this I was experiencing the crashing on both Linux and Windows 8 running on this pc. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/882710 Title: [NVIDIA] Monitor(s) black out and session freezes. "NVRM: GPU at 0000:01:00.0 has fallen off the bus." Status in “nvidia-graphics-drivers” package in Ubuntu: Triaged Bug description: I run Ubuntu 11.10 on a Dell desktop with a dual use video card that goes into two monitors. They normally work great and I have no complaints. When I first upgraded to 11.10, I would occasionally have both monitors randomly black out, and I'd have to restart the computer to get them back. Though that problem seemed to go away, and I wrote it off to package upgrades that fixed a bug. Then, after upgraded unity and a bunch of other packages today it started it again. Three times I've had it black out this morning. I don't know why. Though I often use hotkeys to slide between workspaces, and one of the blackouts happened during a slide.
