Can't get TwinView to work no matter what

Hey all,
I have an Nvidia 8800 GTS 512. I've got the 304.xx driver (and just this driver) installed, as well as kernel headers. I can't seem to get Twinview to work at all.
In nvidia-settings, I have TwinView enabled.

Here's my xorg.conf:

And here's my 10-monitor.conf in /etc/X11/xorg.conf.d/:

EndSection

Section "Device"
    Identifier     "Card0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"

    #refer to the link below for more information on each of the following options.
    Option         "MetaModes"          "1280x1024, 1280x1024"

    Option         "MetaModeOrientation" "DVI-I-2 LeftOf DVI-I-3"
EndSection

Section "Screen"
    Identifier     "metaScreen"
    Device         "Card0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "True"
    SubSection "Display"
        Modes          "1280x1024"
    EndSubSection
EndSection

Thanks!

Re: Can't get TwinView to work no matter what

I see you actually did something similar to what the wiki says on the 10-monitor.conf. That xorg.conf is just not gonna give you anything, other than problems. Remove it.

Section "Device"
    Identifier     "Card0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"

    #refer to the link below for more information on each of the following options.
    Option         "MetaModes"          "1280x1024, 1280x1024"
    Option         "ConnectedMonitor"   "DVI-I-2, DVI-I-3"
    Option         "MetaModeOrientation" "DVI-I-2 LeftOf DVI-I-3"
EndSection

Where do you get DVI-I-2/3 from? From that screenshot you have two connections called DFP-0/1.

Xrandr refers to those displays as DVI-I-2 and DVI-I-3, whereas nvidia refers to them as DFP-0 and DFP-1.

Re: Can't get TwinView to work no matter what

Well, I'm actually not sure why I even asked about that as they are mostly the same thing, could be from being so confused about what you have actually put in your configs. It would probably not make any difference using the connection name as opposed to the display device name. Still, remove that xorg.conf. Try it again and provide the X log.
