Public bug reported: Unable to set up 2 separate X screens on 12.04 (this works on 10.04).
What I did: fresh install of Ubuntu 64bits. Then upgraded. Then try to set up 2 separate X screens (2 monitors). It didn't work on nouveau, nvidia-current, nvidia (post release updates), and nvidia-experimental-310. The behaviour is the same regardless of the driver used: First the 2nd monitor is complete blank, with an X as a mouse cursor (X Windows default?) . This follow the same description follow in this bug: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/885989 'killall nautilus' shows the default background, but no top panel, no launcher, and same mouse cursor. Launching any instance of nautilus blanks the screen again. I dug a little further and I found this bug: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/661450 running 'DISPLAY=:0.1 compiz --replace' offers a little improvement: top panel appears, as the unity launcher. However, no windows decorations and all windows open stick to the upper left corner. They can't be moved. After restarting the machine all back to zero. I went to #ubuntu, but there's no other advice besides install ppas like swat and edgers. I'm willing to provide any other information and make any tests you request. Kind Regards.
