    Il DE Cinnamon utilizza l'accelerazione video, quindi dovrebbe
    essere necessario installare in chroot il driver 3d della scheda
    video (client), come suggerisce il sito che ho linkato, anche se il
    funzionamento non è confermato.<br>
    <br>
    Ho appena acquistato una nuova SD per fare esperimenti sul Raspberry
    senza incasinare la mia configurazione per uso "multimediale", ora
    devo solo trovare il tempo per testare lo "scatolino" come thin
    client LTSP.<br>
