Hi everyone,

i have tried ubuntu 11.04 and now linux mint 11, everything works fine, but when i try to shutdown the pc or try to logout then i get a flickering green screen. It's just lasts for a second or something. After the pc shuts down / or logs out as it was told to do.
It really annoys me, because all the other thinks are just working fine.

I'm using the fglrx driver, which was proposed by the system.
