Connecting two monitor to a NVIDIA card without the proprietary driver

Sunday, November 16th, 2008

For a long time I searched for a way to connect two monitors to an NVIDIA graphic card without using the proprietary nvidia driver (mainly because I wanted to try use OpenBSD and 64bit FreeBSD).

Somehow I never read nv’s (the free Xorg driver) man page – until today. And there it is, clear as crystal:

Option "Dualhead" "boolean"
    Enables simple VBE-based dual head mode.  This sets the same resolution on both outputs and lays them out
    side-by-side.   The screens will be panned together as one big metamode if the virtual desktop is larger than both
    screens combined.

So I just had to change my Xorg config from:

Section "Device"
    Identifier     "Card0"
    Driver         "nvidia"
    Option        "TwinView"


Section "Device"
    Identifier     "Card0"
    Driver "nv"
    Option	"Dualhead"

So simple!
