Quale modeline per 768x480

[xwang]

Ciao a tutti.
Ho uno schermo 16:10 (risoluzione nativa 1280x800) e dovrei avviare una sessione X a 768x480.
Cosa devo fare?
Aggiugere una modeline opportuna?
Sotto c'è il mio attuale xorg.conf, ma se leggo il file di log mi dice che la risoluzione 768x480 non è accettata.
Mi aiutate?
Grazie,
Xwang
