Comment 37 for bug 88431

I have the same problem and was able to locate the cause I think.

I'm using two monitors and have the following device section in the xorg.conf.

Section "Device"
        Identifier "nVidia Corporation G72M [Quadro NVS 110M/GeForce Go 7300]"
        Driver "nvidia"
        BusID "PCI:1:0:0"
        Option "TwinView" "on"
        Option "TwinViewOrientation" "Clone"
        Option "MetaModes" "1280x1024, 1280x800"
        Option "TVOutFormat" "COMPOSITE"
        #Option "ConnectedMonitor" "TV"
EndSection

With TwinView "On" the module fails to load and I think it is because it does not
recognize the meta modes correctly. (See python failing with a list error below).

Error output:
