Default Re: Problem with different meta-modes naming 3 displays (max 2 per meta-mode)

I see this is a pretty old post, but I am trying to do the exact same thing on similar hardware. CRT-0 and DFP-1 are Dell monitors hooked up to my dock and DFP-0 is the built-in LCD in the laptop. I was thinking that setting "Option" "TwinViewXineramaInfoOrder" to "CRT-0, DFP-1, DFP-0" would make the driver use CRT-0 and DFP-1 when I was docked, but fallback to DFP-0 when I was undocked, but it's not working that way. Getting this is in Xorg.log:

[163351.286] (II) NVIDIA(0): Display Devices found referenced in MetaMode: CRT-0, DFP-0,
[163351.286] (II) NVIDIA(0):     DFP-1
[163351.286] (WW) NVIDIA(0): There are only 2 heads available, trimming display device list
[163351.286] (WW) NVIDIA(0):     from "CRT-0, DFP-0, DFP-1" to "CRT-0, DFP-0".
[163351.353] (II) NVIDIA(0): Assigned Display Devices: CRT-0, DFP-0
[163351.353] (II) NVIDIA(0): Validated modes:
[163351.353] (II) NVIDIA(0):
[163351.353] (II) NVIDIA(0):     "CRT:nvidia-auto-select+0+0,DFP:nvidia-auto-select+1280+0"
[163351.353] (II) NVIDIA(0):     "DFP:1920x1200+0+0"
[163351.353] (II) NVIDIA(0): Virtual screen size determined to be 3200 x 1200
Here is the Screen section of my xorg.conf:

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "1"
    Option         "TwinViewXineramaInfoOrder" "CRT-0, DFP-1, DFP-0"
    Option         "metamodes" "CRT: nvidia-auto-select +0+0, DFP: nvidia-auto-select +1280+0; DFP: 1920x1200 +0+0"
    SubSection     "Display"
        Depth       24
I've been working on this quite a bit and it seems like I'm so close. Anybody have any clues/hints? Using Fedora 13 if it matters.
