How to disable/enable indicator(status) in ubuntu using terminal.
You are running Unity. Maybe try, as suggested here, disabling the service providing the infos for the indicators (therefore, avoiding unity indicators to launch), type :
sudo mv /usr/lib/unity/unity-panel-service ~/unity-panel-service.bak
(You basicaly move the service file to a backup file in your home directory, to undo, simply remove them tho other way around).
