[Bug 638352] [NEW] Screen flashes randomly during use. Reboot necessary.

 

Public bug reported:

Binary package hint: xorg

System works normally for a period of time, then some trigger (haven't
determined what) causes the screen to start flashing with vertical white
bars in the upper right hand corner.  I can't switch virtual terminals
or interact with the system at all except by pressing the power button.
A short press causes the system to power down normally with the monitor
properly displaying the Ubuntu shutdown screen.

I didn't have this problem until I upgraded to Lynx.  I have tried a
fresh install and saw no improvement.

Any help?
