Public bug reported:
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
