Bug Description
I run Oneiric alpha 2 64+mac live CD. Plugging in an external monitor with a DVI cable causes the screen corruption.
The laptop's main screen splits into two halves. The top one keeps showing whatever it was showing when the monitor was plugged.
The bottom half displays properly.
The external monitor is fully black except for the menu bar at the top.
Unplugging the monitor makes everything work again.
Using a VGA cable gives almost the same results, except that the split does not happen at the middle of the screen but rather about a quarter from the top. The top also displays black rather than what was there originally.
