Sometimes, after installing an application (Codeweavers Crossover to be more specific on this case) it fails to show on the Dash until you logout and back on. That happens with Unity and GNOME Shell, remember that with GNOME Fallback it is automatically added as a menu.

Is there a command that allows one to force a refresh on the cached application launchers in the Unity Dash or the GNOME Shell desktop environments?


To restart the GNOME Shell (no logout):
Press ALT + F2 and type r or restart and press enter

To restart Unity (no logout):
Press ALT + F2 and type setsid unity or unity --replace
