Comment 6 for bug 294309

Additional information:

After running the commands listed above (xrandr -o right, glxgears, xrandr -o normal), the screen briefly flashes a garbled video output that looks almost like a checkerboard of smaller sections with alternating blue and red lines. An image of a cursor is also visible...I'd attach a photo, but I have no camera here.

The xserver then restarts with a gdm login screen, this time on vt9 instead of vt7.

I can then switch to a virtual terminal, but it is unusable--the far right side of the screen has alternating blue and red lines and the image of a cursor. There is no login prompt.

I didn't notice the caps lock led flashing...

I am unable to reproduce this now. I did a clean install, and got the xserver to crash. I then installed updates (really only the kernel with a base install), and now it won't crash... I've spent the last 30 minutes restarting/rebooting, rotating, running glxgears, etc, and the xserver hasn't crashed again. (I did find out that glxgears has some interesting artifacts when another window has focus--see attached screenshot). I also haven't seen the problem with the vt display being corrupted upon suspend/resume...

I'll continue to play with it, and if I see the crash again I'll post here.
