Gnome pannello applicazioni

[Vagolando]

Ciao a tutti!
Ho gnome 2.12 su un ubuntu breazy. Faccio il login con il mio utente, carica tutto ma non riesco ad usare il pannello, nè con il muose ne con alt+F1 e le icone sulla destra che mi indicano lo stato della rete, data e ora e audio sono scomparse.
QUalcuno ha qualche idea?
Grazie
