Debian - Configurazione scheda video nVidia Corporation G73 [GeForce 7600 GT]

Quest'oggi ho iniziato la "debianizzazione" di un computer, la prima difficolta` e` stata la configurazione della scheda video.
Non che fosse difficile, tutt'altro, ma non trovavo le informazioni giuste, finche` non sono capitato qui: http://wiki.debian.org/NvidiaGraphicsDrivers#Installation-1
Ho semplicemente digitato (ovviamente come user 'root'):

apt-get install nvidia-glx

Ho sistemato il file "/etc/X11/xorg.conf" secondo le mie esigenze:
