I had the same problem but managed to work around it by changing the mouse_button_modifier in metacity (inside the configuration editor) from <Super> to <Alt>.
Perhaps this happens because Gnome-Do has the keybindings of <Super>+Space, and metacity doesn't like it. -- Gnome Do has visual problems when run with Metacity's compositing manager https://bugs.launchpad.net/bugs/206870 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
