Comment 0 for bug 864784

I upgraded to 11.10 and am no longer able to use my external monitor with my laptop while using Unity. It was fine with 11.04.

I have the latest NVIDIA driver installed via jockey.
I tried both drivers listed, both act the same.

Repo:
I use the Nvidia-Settings manager tool to turn on my secondary monitor with twinview. (As usual)
the screens com up but the graphics are messed up, then if i'm lucky unity will crash and I'll be left with a blank screen with just my wallpaper left.

Unity 2d works as expected.
