Public bug reported:
A few weeks ago I upgraded to 12.04 because I wanted to test it. I did
the update "in 2 parts" because my computer crashed the first time. A
few days ago i updated a few packages with apt-get (about 20 packages I
think).
Suddenly my dual-monitor setup did not work any longer (same bug as
written below), I decided to reinstall Ubuntu to get a clean OS.
Installing fglrx-updates with jockey didn't work so i installed it
through the terminal.
Then i set up up my screens in amdcccle (multi-desktop). That way it worked
perfectly in 11.10.
Now the only thing i got is a white primary screen and a "working" secondary
screen. If my mouse enters the left screen, the cursor changes to an "X". I can
right click on the blank screen and the menu opens, but i can not have any
windows on the screen. I can change which monitor works either my left or my
right screen by editing xorg.conf.
If I activate Xinerama in amdcccl both screens work, but i only get
Unity2D automatically at login and everything feels really slow. In
11.10 both screens worked without Xinerama (i had Xinerama turned off
because i have the top-bar of unity on both screen, which i don't like)
My graphics card is an AMD Sapphire 6850.
Edit: I can't remember exactly and i can't test it right now but I think
with open source drivers it worked.
