White screen on second monitor with X Screen (12.04)
I just installed Ubuntu 12.04 and I'm having a problem with my second monitor when I try to use them as seperate X Screens. When Ubuntu starts and I log in I first see the background for less than a second and then the second monitor becomes white and when I go on it with my mouse I get an "x" pointer. When I right click on that monitor I get a dropdown menu which is the same like on the working screen when I right click the background.
I have a NVidia GeForce GT240 card and the two monitors are connected through DVI and VGA ports. I tried uninstalling the default graphics drivers and downloading / installing the latest drivers from nvidia.com, but still nothing is fixed.
Any fixes?

Can you give the output of:
sudo lshw -C display; lsb_release -a; uname -a; dpkg -l | grep nvidia
Thanks

I have the same problem and after doing some searching it looks like it is pretty common. Maybe connected to this bug?

After several days of researching / googling + working it out on IRC @ #ubuntu, I turned to a Twinview workaround which works perfectly for me now.

What was the workaround?! I can't find one...
Just use Twinview instead of X Screens. Worked for me when I was on Ubuntu (switched now).

Actually after I posted that I changed to separate x-windows with Xinerama enabled, that worked perfectly. Now to get Wine games working in fullscreen... Thanks!
