My computer has integrated graphics Radeon HD3200, that brougt me several problems with different versions of Ubuntu. The only one that I couldn't manage is that every time I restart the PC I have to login into Gnome or Openbox twice, cause the first time Xorg doesn't get my mouse clicks. It handles mouse movements and all keyboard orders. When I logout and come back login in, problems are gone. This problem happens also with and without fglrx. Same with or without compiz. And either if I use Gnome or Openbox.
No errors (EE) in Xorg.log.
