Comment 38 for bug 1033533

My version of the crash is an initial [drm] nouveau 0000:01:00.0: GPU lockup - switching to fbcom \n and similar repeated messages of "Failed to idle channel 1. (or 2), all interleaved with full screen patterns of color block patches.

It is interesting that while I see mp4 videos from edx.org classes, what really exacerbates the problem is alt-tab between screens. My first real indication of a problem is when alt-tab produces a solid triangle of color on the bottom right half of the display. the diagonal goes from the bottom left of the left monitor to the top right of the right monitor. Shortly after that the system becomes unusable, and power button for reboot.

I have not gotten to the point of opening up port 22 to remotely connect to the system.

This is a clean install of 12.10, and all of the updates are current.
