I've been trying this dual-monitor set-up for the last 2 weeks but with no success. I've readed tones of forums and tutorials but nothing seems to work.

I'm trying to get both screens through the 2 DVI's GPU connectors being displayed with xrandr -q as DVI-I-1 (connected) and DVI-D-0 (disconnected).

In theory by typing sudo nvidia-settings on the terminal I should be able to see and configure TwinView and save the config on to the /etc/X11/xorg.conf but nvidia doesn't seems to detect the screen.

I've tried with many different drivers from the additional drivers utility in ubuntu and also manually installed from the nvidia site but in they were not able to detect the second monitor.

Lastly the closest I've got to get it working was with the following xorg.conf configuration:

Section "ServerLayout"
    Identifier     "TwinLayout"
    Screen         0 "metaScreen" 0 0

Section "Monitor"
    Identifier     "Monitor0"
    Option         "Enable" "true"

Section "Monitor"
    Identifier     "Monitor1"
    Option         "Enable" "true"

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

    #refer to the link below for more information on each of the following options.
    Option         "HorizSync"          "DFP-0: 28-33; DFP-3 28-33"
    Option         "VertRefresh"        "DFP-0: 43-73; DFP-3 43-73"
    Option         "MetaModes"          "1920x1080, 1920x1080"
    Option         "ConnectedMonitor"   "DFP-0, DFP-3"
    Option         "MetaModeOrientation" "DFP-3 LeftOf DFP-0"

Section "Screen"
    Identifier     "metaScreen"
    Device         "Card0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "True"
    SubSection "Display"
        Modes          "1920x1080"

In this case, the second monitor is working but with limited resolution 800x600 and from here also tried many different configurations but non of them allow me to modify the second screen resolution. It doen't feel right anyway to force it like that, as far as I understood the nvidia-settings should detect the second screen just by pluging it.

My conclusion is that the driver doesn't handle properly a secondary monitor that's why I would like to know if some have successfully achieve this with similar hardware or if someone could give me any clue about how to make this to work.

Thanks in advance
