Ho provato a configurare il mio sistema (scheda video ATI radeon 7000 VE
con doppia uscita monitor) per il funzionamento con doppio monitor, ma non
riesco a far funzionare il secondo. Ho proceduto come a seguito:
- Installazione dei driver ati:
rpm -i fglrx-4.3.0-3.9.0.i386.rpm
file /usr/X11R6/lib/libGL.so.1.2 from install of fglrx-4.3.0-3.9.0
conflicts with file from package libxorg-x11-6.8.2-7mdk (questo è il
messaggio generato)
- Settaggio manuale xorg.conf:

Qualcuno ha qualche consiglio?

probabilmente hai sbagliato a scaricare il driver da ati

c'è la versione per xfree e quella per xorg
tu devi scaricare quella per xorg

Beh comunque, dopo mesi di prove, 10 minuti fa mi è partito il secondo
monitor, con la mia scheda ati 7000 ed i driver per la scheda video VESA
2.0! adesso non ho più tempo, la prossima è la configurazione con
xinerama! (premetto che i driver vesa sulla suse NON funzionavano). Poi
eventualmente scrivo 2 righe come promemoria, se interessa a qualcuno.
