Thanks for the response. When I do this a root, I receive the error:
Unable to start the settings manager 'gnome-settings-daemon'.
Without the GNOME settings manager running, some preferences may not take effect. This could indicate a problem with Bonobo, or a non-GNOME (e.g. KDE) settings manager may already be active and conflicting with the GNOME settings manager.
