Cannot set dual display with radeon driver on Oneiric

[Tony Mugan]

Unity fails to load correctly even though the Unity plugin is checked in compiz (verified with ccsm).
I only see the Nautlus menus at the top of screen and the Unity launchbar is missing.

I have tried setting the mirrored display as dual display with gnome-control-center display but it only shows a single "Unknown" monitor which I cannot set as a dual display.

As a related aside, I also cannot set the dual display with fglrx and have tried with both a radeon 5770 and a 5870 so I am sure it is not a hardware fault.

I managed to get this working by cleanly uninstalling the fglrx driver and then reinstalling some components as detailed here.

From the blog in question here is the solution in a nutshell:

There were issues with the AMD proprietary driver (“fglrx”) for both my 5770 and 5870 graphics. After removing the proprietary AMD driver, some residual issues still persist.

sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev* xorg-driver-fglrx
sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon
sudo apt-get install xserver-xorg-video-ati
sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

Hi Tony,
When installing and removing fglrx, did you do this through "Hardware Drivers" app (jockey-gtk)?

The reporter worked around the issue by using open-source radeon drivers and has requested the bug be closed. I am marking it incomplete in case anyone wants to contribute more information.
