I just uninstalled the 290.10 driver and installed the recommended one
via jockey ("Additional Drivers") which is version 280.13.
Unfortunately that didn't solve the problem. Opened up several youtube
videos and clicked around and eventually my system, respectively the UI
locked up again :(
I fear that there's a problem between flash(player) and NVIDIA driver. I
just can remember that this must have started after upgrading to 11.10
and removing those sevenmachines (PPA) flash player version and
installing the one from ubuntu-repos.
