Bug Description
Hi. I hope this is the right place to report this bug.
I'm running ubuntu 12.04 on a laptop with sandy bridge hardware, switchable graphics (intel HD3000 / AMD HD 6770m). I use the latest version of fglrx (12.2) to manage switching between discrete and integrated gpus.
It seems that composited environments like unity3d or gnome-shell won't load from gdm or lightdm when I'm using the integrated GPU. It will log me in but it will just display the background but nothing else.
However I'm able to reload it from tty with "DISPLAY=:0.0 gnome-shell --replace" or "DISPLAY=:0.0 unity --replace" and the environment will be fully functionnal.
Here are some informations about my setup:
