Xorg freeze

[John Larsen]

Interface freezes sometimes when waking up from suspension. Not able to tell the conditions of freezing.

I have the login-screen from suspension enabled.

When it freezes, sometimes the screen stays black where I can move the mouse cursor around and sometimes the frozen desktop appears without showing the login-screen first.
I can press always press alt+f2 to do a system reboot in the terminal.

This did not happen in Ubuntu 11.10
