Today I rebooted my system and for some reason the menu at the top is blank... no global menu, no time, no date, no nothing...

Do you have any idea how this can be rectified?

This can happen if you've changed some Compiz settings which have messed up Unity. You can reset Unity to its default settings.

Resetting Unity:

Hit Alt+F2 and run the following command:

unity --reset

This will only reset the Unity settings in CompizConfig Settings Manager and leave the other CCSM settings intact.

on 14.04.1 this command returns ERROR: the reset option is now deprecated – Antonios Hadjigeorgalis Feb 17 '15 at 15:47
