Dual Port (VGA + DVI)

Dell Precision 390N with Dell 2407WP monitor.

Port 1 connected to DVI. Port 2 connected to VGA on KVM.

At first, with the default xorg.conf, the machine would boot on the DVI port, then switch to VGA port when the gui started. I wanted the gui to be on the DVI port.

First, I ran nvdia-settings
    Under "X Server Display Configuration", Under Display, I chose Configuration to be "Separate X Screen" with Resolution of "1920x1200", then "Save to X Configuration File"

This didn't seem to make a difference.

I edited the new xorg.conf:

Under "ServerLayout", I added:
        Screen      0 "Screen0" LeftOf "Screen1"
        Screen      1 "Screen1" 0 0
        Option      "Xinerama" "on"
        Option      "Clone" "off"

Under "Module", I added:
        Load "nvidia"
(but I don't know if this is really needed)

Under "Videocard0", I added:
        Option      "ConnectedMonitor" "DFP"

The rest of the configuration file looks like this:
....
Section "Monitor"

    # HorizSync source: edid, VertRefresh source: edid
### Comment all HorizSync and VertSync values to use DDC:
        Identifier   "Monitor0"

        VertRefresh 56.0 - 76.0

EndSection

        EndSubSection
EndSection

        Identifier "Screen1"
        Device     "Videocard1"

                Modes    "1900x1200" "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
        EndSubSection
EndSection

After rebooting, the gui was on the DVI port.

The well mentioned about the VGA adapter in this post. I hope that we will get this kind of stuff in the future also. https://www.pcsupportnumber.co.uk/blog/fix-error-code-0x3e91001-system-error-1001/
