Twinview problem with GeForce FX 5500

The two monitors I'm using are a Compaq FS740 and a CTX 17" VL700.

When I start Mandrake, both of the monitors display the same thing. Then when I log in, only one displays something.

This is what the Device part of my XF86Config looks like:

Code:

Section "Device"

    Identifier "device1"

    BoardName "NVIDIA GeForce FX 5500"

    Driver "nvidia"

    Option "DPMS"

    Option "IgnoreEDID" "1"

    Option "TwinView"

    Option "SecondMonitorHorizSync" "30-72"

    Option "SecondMonitorVertRefresh" "50-130"

    Option "TwinViewOrientation" "RightOf"

    Option "ConnectedMonitor" "CRT,CRT"

    Option "RenderAccel" "true"

    Option "MetaModes" "1024x768,1024x768"

EndSection

With that config, X won't start. It gives me this error:

Code:

(EE) NVIDIA(0): Failure to construct a valid mode list: no modes remaining

(EE) NVIDIA(0): *** Aborting ***

(EE) Screen(s) found, but none have a usable configuration



Fatal server error:

no screens found

I think it has something to do with the MetaModes line. X will start if I get rid of the line or change it to "1024x768". I've tried changing it to "1024x768,1024x768;800x600,800x600;" and others, but I still have to either get rid of it or change it to just "1024x768". Any ideas?

Can we see the 'screen' section of your xorg.conf....
If you want, I have my xorg.conf up on my website. It is set up two run 2 identical monitors with twin-view. Maybe it will help:

Yeah, here it is:

Code:

Section "Screen"

    Identifier "screen1"

    Device "device1"

    Monitor "monitor1"

    DefaultColorDepth 24

    

    Subsection "Display"

        Depth 8

        Virtual 1024 768

    EndSubsection

    

    Subsection "Display"

        Depth 15

        Virtual 1024 768

    EndSubsection

    

    Subsection "Display"

        Depth 16

        Virtual 1024 768

    EndSubsection

    

    Subsection "Display"

        Depth 24

        Virtual 1024 768

    EndSubsection

EndSection

Ok, yeah...
Change all those 'Virtual' lines to:
Modes "1024x768"
