gnome-control-center is empty when started over ssh
If you connect to a remote machine using "ssh -X" or "ssh -Y" then gnome-control-center launched from ssh might show up as empty without any options / modules. To solve this problem launch gnome-control-center over ssh using:
env XDG_CURRENT_DESKTOP=GNOME gnome-control-center
