After installing Cairo-dock, the bluetooth indicator disappeared when I restarted my laptop. Bluetooth is working fine. But the bluetooth-indicator at top left of the panel is not showing up anymore. I have to go to System Settings>Bluetooth to add/remove bluetooth devices. How to bring back the bluetooth indicator?
