xorg.conf configuration for nVidia TwinView on the Dell D620

I managed to get TwinView working on the Dell Latitude D620 under Debian GNU/Linux and I’ve been using it for a few weeks now without any problem whatsoever.

The key section in /etc/X11/xorg.conf is this:

Section "Device"
        Identifier      "Generic Video Card"
        Driver          "nvidia"
        BusID           "PCI:1:0:0"
        Option "TwinView"
        Option "MetaModes"                "1280x1024, 1440x900; NULL, 1440x900"
EndSection

Section "Monitor"
        Identifier      "Generic Monitor"
        Option          "DPMS"
        HorizSync       28-72
        VertRefresh     43-60
EndSection

Section "Monitor"
        Identifier      "External Monitor"
        Option          "DPMS"
        HorizSync       28-72
        VertRefresh     43-60
EndSection

I’m using an external 1280×1024 LCD, and I use the KDE control center (Peripherals/Display) to switch between metamodes. The nice thing is that whenever the X server starts and it doesn’t sense the external display it automagically defaults to using only the built-in display. Moreover, TwinView handles gracefully the “hole” below the 1440×900 display. Now what I’d really like to do is to specify that the primary monitor is the built-in display instead of the external LCD, but that can wait a bit longer.

Of course, you can download the complete xorg.conf I’m using, with my finely-tuned (right) TrackPoint and TouchPad configuration.

    You info was very valuable. Only thing I did was not use Twinview. Works great.

  2. I have a the same laptop, and use your xorg.conf. But I don’t get the server to run with it, only when I recplace nvidia with the nv driver. I have a pretty complete description of the issue at

    http://openlib.org/home/krichel/debian_dell_latitude_d620/

    It is the last of the four issues I had with the machine, three still open, one (sound) fixed.

    Awesome read. Really handy info.

    My D620 is much, much happier today!

    Using the built-in NVIDA loader and looking at many web sites for further help, I just could not get the driver to load.

    I think a critical element you put in was commenting out this line: Load “dri”
