I'm having a problem with setting up a dual screen display. I'm using Gentoo, and the last time I had it installed it set up KDE to have two seperate desktops, one for each screen. It wasn't seperate X sessions because I could drag windows between screens, and I know you can't with seperate X sessions.

But recently I reinstalled Gentoo and now it stretches one desktop across both screens, which is annoying because windows always spawn in the crack between the screens, and it stretches my wallpaper. I've even using the same xorg.conf, and the same nvidia-drivers. Is there any way to get it have two desktops, without using seperate X sessions.

Here is my xorg.conf:

Code: Select all

Section "Monitor"
    # HorizSync source: edid, VertRefresh source: edid
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "DELL E171FPb"
    HorizSync       31.0 - 80.0
    VertRefresh     56.0 - 75.0
    Option         "DPMS"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce 8800 GTS"
    #Option         AddARGBGLXVisuals "true"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "1"
    Option         "TwinViewXineramaInfoOrder" "DFP-1"
    Option         "metamodes" "CRT: 1280x1024 +0+0, DFP: 1680x1050 +1280+0; CRT:1280x1024 +0+0, DFP:$
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection


Strange, TwinView and KDE4 (You have KDE4?) working really nice together here.

What happens if you remove the following line form your xorg.conf:

Code: Select all

     Option         "TwinViewXineramaInfoOrder" "DFP-1"

Didn't change anything.

You can try to replace it with this line:

Code: Select all

Option         "TwinViewXineramaInfoOrder" "DFP-0"

and maybe have a look at the log file.

Try to change 'metamodes' to 'MetaModes'.

Nope, neither worked.

Just curious... did you use the nvidia settings to setup two desktops, or did you change the xorg.conf manually?

Yes, I used the nvidia tool. But I'm using the same xorg.conf that I had on my last install of Gentoo. I backed it up and brought it over to the new install, and it's not working the same.

Have you tried generating a basic xorg.conf and setting it up again with the nvidia settings tool?
