Dual-Monitor in 12.04 with fglrx?

Asked by joni on 2012-03-27

Just installed ubuntu 12.04 and wanted to get my dual monitor setup working. 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 left screen and on the right screen there is no unity launcher. If my mouse enters the left screen, the cursor changes to an "X" and i can even right click and the menu opens, but i can not have any windows on the other screen.

If i activate Xinerama in amdcccl both screens work, but i only get Unity2D automatically.

How can i get the 11.10 behavior back?

Btw. I have an AMD 6850.
