This happened to me on feisty, and I am not using either nvidia or beryl (or compiz). So I'm reattributing it to gdm.

I had to zap the server because my gnome-panel had crashed. (Well, I guess I could have tried killing the gnome-session instead, but gdm ought to be robust against the server unexpectedly exiting.)

I couldn't seem to get much debugging information, except this from the daemon.log:
