Public bug reported:

Binary package hint: xorg

Since I upgraded from Ubuntu 10.04 to 10.10, the monitor displays
correctly for a couple of seconds, then turns black for a fraction of a
second and then repeats the on and off sequence, making the computer
nearly unusable.

The whole sequence is periodic, not random.

Another bug reported earlier (#606987) persists in this release as well,
perhaps with the exception that restarting the computer (as opposed to
turning it on after a shutdown) gives a normal logon screen. (I only
used Restart a couple of times since the upgrade.)

Thanks and regards
