The following message are appeared after I upgrading my Hardy:
There was an error starting the GNOME Settings Daemon.
Some things, such as themes, sounds, or background settings may not work correctly.
The last error message was:
Failed to connect to socket /tmp/dbus-n9Y8sWjrkS: Connection refused
GNOME will still try to restart the Settings Daemon next time you log in.
It’s always appeared every system log in. My desktop appearance is look so bad. But when I reinstalling dbus, dbus-x11 and purging some setting (like delete .dbus directory on my HOME dir, etc), it never comes again 😀
