Title:
  Random screen corruption

Status in xorg package in Ubuntu:
  New

Bug description:
  I don't know of anything I am doing to trigger this problem. My screen
  will randomly go black for about 2 seconds and then come back on with
  horizontal lines over everything. Sometimes I can see my work in the
  background but it's all scrambled. The mouse pointer stays on top and
  I can click on things in the background but the buttons I try to click
  on are mixed together, overlapping each other  or stretched across the
  screen so I can't tell which button I am clicking. If I use keyboard
  short cuts such as Alt-Tab to change what is on the screen, the
  distortion will usually partially clear up. After switching between
  programs about two or three times, all that is left is a couple of
  lines at the top of the screen which eventually disappear. The first
  time this happened to me, I had booted from a flashdrive but after
  installing Ubuntu  to my harddrive, it's still happening. I am usually
  using firefox at the time it happens but I have seen it happen to my
  desktop with nothing running. I see it happen randomly about once/hr.
  I have noticed that all the buttons and links on the screen become
  unresponsive a few seconds before it turns off
