Xorg - Xinerama monitor problem.

Hi everyone, I got a little problem. After a little work I finally got my Xinerama to work, problem is that it seems to be using the wrong monitor as the main one, why do I think that? If I start a fullscreen program it starts on the other monitor, and same with gdm/xdm. I want the left monitor with the 1240x1028 resolution to be the main one, not the right with 1024x768.
My setup:
2.6.19-ARCH standard kernel.
Nvidia graphic-card with the "nvidia" drivers from pacman.
The left monitor is using the DVI-output from my graphic-card and the right is using the VGA-port, both TFT's.

My config:
xorg.conf (it got some unrelated errors, so no need to comment that)

Simply switching the places in the ServerLayout section wont work as it will make both screens use 1024x768.

Re: Xorg - Xinerama monitor problem.

Here's what my xorg.conf looks like, though I'm using TwinView, which I found easier to configure, since you don't have to define the second screen, except in the MetaMode option.

Section "Device"
        Identifier  "Card0"
        Driver      "nvidia"
        VendorName  "nVidia Corporation"
        BoardName   "GeForce Go 7800 GTX"
        BusID       "PCI:1:0:0"
        Option      "RenderAccel"
        Option      "NoLogo" "1"
        Option      "TwinView" "True"
        Option      "UseEdidFreqs" "True"
        Option      "MetaModes" "DFP-0: 1920x1200, CRT-0: 1280x1024"
        Option      "TwinViewOrientation" "DFP-0 LeftOf CRT-0"
        Option      "TwinViewXineramaInfoOrder" "DFP-0"
EndSection

Re: Xorg - Xinerama monitor problem.

Thanks for your reply, seems that my dns-servers has been acting up so havent visited for a few days.
Will look into twinview, thanks

Edit
I now got twinview problems (I know, I cant do anything myself :E)
Current problem: with my config (linked below), it does work, but it seems to behave like both monitors where in 1240x1024, which it shouldn't.
twinview conf

If I uncomment: Option      "MetaModes" "DFP-0: 1240x1024, CRT-0: 1024x768", it will only start the left monitor in 1024x768, and wont use any other display, but both displays work just fine if I put both values to 1024x768 instead of using different ones.

Please be patient with me, and thanks for the help.
