VirtualBox: eseguire in modalità FullScreen

Di default, la modalità Full Screen di Virtual Box si limita a occupare tutto lo schermo con una cornice nera, lasciando il sistema guest in una finestra molto ridotta. Per fortuna, per ottenere l’effetto “completo”, sono sufficienti pochi passaggi.

Ecco un semplice esempio calato su Ubuntu 10 come sistema guest (il sistema host è Mac OS 10.8 Mountain Lion, ma ha poca influenza):

  1. Avviare la macchina virtuale
  2. Dal menù di VirtualBox, scegliere Dispositivi > Installa Guest Addictions…
  3. Si avvierà in maniera più o meno automatica una serie di installazioni, che devono tutte essere completate
  4. Riavviare la macchina virtuale
  5. Al termine del boot, entrare in modalità a schermo intero, che ora sarà “davvero intero”
Buon lavoro.
