Bug Description
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
