Quello che segue è il contenuto delle sezioni “device”, “screen” e "server layout" per l’utilizzo di più monitor con schede video nVidia. A differenza dell’utilizzo con xinerama i due monitor condividono un solo framebuffer ottenendo così una performance migliore. In conseguenza di ciò non è necessario duplicare le sezioni “device”, “screen” e “monitor”. Le opzioni in grassetto vi permettono di stabilire, nell’ordine, la posizione dei due monitor e quale dei due utilizzare come principale.

Qui di seguito potete leggere la sezione “device” di xorg.conf per l’utilizzo di due monitor su schede video ATI. A differenza della configurazione per nVidia questo metodo non è stato verificato poiché non possiedo schede video ATI. Questa sezione fa riferimento alla configurazione della sezione Device relativamente ai driver proprietari di ATI. 

                        Section "Device"
