X-Windows sees all my monitors, but gnome 3 does not

[Scott_Schumacher]

So, my xorg.conf looks like this:


Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0" 0 0
Screen 1 "Screen1" RightOf "Screen0"

# Option "Xinerama" "1"
EndSection


Section "Monitor"
Identifier "Monitor0"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
EndSection


Section "Monitor"
Identifier "Monitor1"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
EndSection


Section "Monitor"
Identifier "Monitor2"
Option "VendorName" "ATI Proprietary Driver"

EndSection


Section "Monitor"

EndSection



X-windows works, but gnome 3 only uses the first monitor

Any Ideas?

Thanks
