This might be of some help. I had a very similar problem when trying to
configure my Dell D800 laptop to use the built-in display and an
external digital display as two separate screens. Setting them up with
twinview worked fine, but I really wanted two screens. In the end the
problem turned out to be that I needed to explicitly include the
"ConnectedMonitor" option to tell the driver which particular display
device was associated with which screen. Something like this:
Section "Device"
Identifier "nvidia0"
Driver "nvidia"
BusID "PCI:1:0:0"
Screen 0
Option "ConnectedMonitor" "DFP-0"
EndSection
Section "Device"
Identifier "nvidia1"
Driver "nvidia"
BusID "PCI:1:0:0"
Screen 1
Option "ConnectedMonitor" "DFP-1"
EndSection
If I failed to do this then the driver appeared to actually try to
display both screens on the same physical display, obviously not what I
was looking for. When I used an analog external monitor I was able to
get by with:
Section "Device"
Identifier "nvidia0"
Driver "nvidia"
BusID "PCI:1:0:0"
Screen 0
Option "ConnectedMonitor" "DFP"
EndSection
Section "Device"
Identifier "nvidia1"
Driver "nvidia"
BusID "PCI:1:0:0"
Screen 1
Option "ConnectedMonitor" "CRT"
EndSection
I suppose this is because the driver was able to determine that the
built-in monitor was the DFP and the external monitor was the CRT so I
didn't have to add the -0 and -1 identifiers on the end, but with both
monitors were digital setting just DFP (or autodetect) always failed
until I learned to add the identifier string to the end.
Hope it helps.
Later,
Tom
