Dual monitors with Nvidia 7200 GS?

[kozimodo]

Hi all -

I just bought an eVGA graphics card so that I could used a dual monitor setup but I'm having a bear of a time figuring out how to set it up. Any one gotten it to work with this card?

Cheers!

I've gotten the dual head setup working with xrandr:

xrandr --output DVI-I-1 --right-of VGA-1

I suppose I could put this in a script and start it on login but that seems inelegant to me.

But can't figure out how to set up an xorg.conf file that will do it. Any help would be much appreciated. My current xorg.conf file is:

Section "InputDevice"
        Identifier      "Generic Keyboard"
        Driver          "kbd"
        Option          "XkbRules"      "xorg"
        Option          "XkbModel"      "pc105"
        Option          "XkbLayout"     "us"
        Option          "XkbOptions"    "lv3:ralt_switch"
EndSection

        Driver          "mouse"

        Option          "Emulate3Buttons"       "true"
EndSection

EndSection

Are you open to using the proprietary nvidia driver? They have a few dual monitor options in their setup program that are pretty easy to configure.

I tried the proprietary drivers (the old one, the current one and the x-swat current one) and only 1 monitor is recognized.

Good point... that could be because the evil VGA adapter might not have DDC so the video card doesn't know much about the VGA display. I got around this by adding my monitor manually to the xorg.conf -- with the appropriate HorizSync and VertRefresh numbers (you have to find these for your monitor).

e.g.:

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "ViewSonic"
    ModelName      "VP171b"
    HorizSync       30.0 - 82.0
    VertRefresh     50.0 - 85.0
    Option         "DPMS"
    # HorizSync source: builtin, VertRefresh source: builtin
    #    HorizSync       28.0 - 55.0
    #    VertRefresh     43.0 - 72.0
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    Option         "TwinView" "1"
    Option         "TwinViewXineramaInfoOrder" "DFP-0"
    Option         "MetaModes" "DFP: 1920x1080 +0+0, CRT: 1280x1024 +1920+0; DFP: 1920x1080 +0+0, CRT: NULL"
        Option         "ConnectedMonitor" "DFP-0, CRT-1"
    DefaultDepth    24
    SubSection "Display"
        Depth       24
    EndSubSection

Unfortunately it's the DVI monitor that's not recognized. I tried setting up the monitor myself in the xorg.conf file but that didn't work either. Thanks anyway.

I have to think that the Nouveau drivers will work since xrandr gets it right -- it's just a matter of figuring out how to set up the xorg.conf.

I got it working following these instructions!

For anyone interested, my xorg.conf is:
