This may be the same bug I'm having. Dell XPS M1330 laptop NVIDIA 8400M
It happens randomly, usually after a day or two. It's never happened before upgrading to Natty, and I've used Kubuntu on this system since 8.04 Hardy. The first time it happened I was able to reboot, but the second time the system froze while logging out, to the point where I couldn't switch VTs. I had to SysRq+B to reboot, so the kernel wasn't frozen, but no other keys seemed to have any effect. ** Attachment added: "Video of display corruption (sorry it's upside down...dumb iPhone)" https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/780669/+attachment/2134182/+files/IMG_0838.MOV -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/780669 Title: Screen corruption -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
