I had this issue on Lucid 10.04 upgraded from 9.10 it is probably a duplicate of: Metacity - https://bugs.launchpad.net/metacity/+bug/150721 GDM - https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/526379 Gconf - https://bugs.launchpad.net/ubuntu/+source/gconf/+bug/293535
simply a side effect of Metacity running twice as "sudo ps aux | grep metacity" shows, rm ~/.config/autostart/metacity.desktop solved it for me .
