Ciao a tutti, non riesco a settare la frequenza del monitor a 60 Hz 
(come consigliato dal produttore).

Il monitor e' un Philips LCD 170S 17" e la scheda video e' una Intel 945G.

Questo e' il mio file xorg.conf:

Section "Device"
        Identifier      "Intel Corporation 945G Integrated Graphics Controller"

Ho provato a seguire le istruzioni trovate qui: 
http://www.ubuntuforums.org/archive/index.php/t-95240.html e qui 
http://ubuntuforums.org/showthread.php?t=63394 ma se vado in 
Sistema-->Preferenze-->Risoluzione Monitor la frequenza rimane a 75 Hz :(.



Come posso fare?
