Default Re: What are my options? Need three dual-link DVI outputs

I thought XGL had the same limitation about 3d over multiple devices just like X did when using xinerama so I guess the fact I am already running XGL just makes things easier. Looking at that link I think I got my xorg.conf setup good:

Code:
# Any number of monitor sections may be present

    #Option      "DPMS"

    VertRefresh 10 - 200

EndSection

Section "Monitor"

    Identifier  "Dell 3007WFP"
    #Option      "DPMS"

    VertRefresh 10 - 200

I am assuming that the second video card will be PCI:5:0:0 but I haven't received it yet (bought a gtx 460 off newegg). This should hopefully allow me to use 3 montors for a total of 15.23 megapixels of desk-top real-estate.

Come Tuesday night I will be bringing in my 3007WFP into work and I hope to have received the gtx 460 by then so hopefully I can report back on whether or not I got thinks working properly or not on early Wednesday.
