I have a Dell 8100 laptop with the following video card built-in:
01:00.0 VGA compatible controller: nVidia Corporation NV11 [GeForce2 Go] (rev b2)
When the display is flipped down and then flipped back up the display the
display is split in two where the bottom half is on the top of the screen and
the top half is on the bottom.
I can work around this by hitting CTRL-ALT-F1 then ALT-F7 and the screen
redisplays as it should.
This happens each time and completely repeatable.
Does this still happen with a current release of xorg?
I'm closing this bug due to the lack of inactivity. If the problem still
persists, please reopen.
