I just installed the 64bit version of 11.1, and with very minimal effort, got wireless and Compiz effects working on a Compaq V2410us laptop. Couldn’t accomplish this with either of 2 flavors of Ubuntu or Fedora this easily. Good job!
Now for the issue. When I set the top right corner to activate the window picker (Expose’ type feature I think), the windows move & resize, the screen darkens slightly, but the desktop & windows become unresponsive. The mousepointer still moves, but ctrl-alt-backspace, ctrl-alt-F1, etc. do nothing. I have to hold the power button down and do a hard restart.
