Ubuntu 9.10 Karmic Nvidia-settings parse fail with xorg.conf

There is a bug in Ubuntu 9.10 Karmic with the default /etc/X11/xorg.conf involving Nvidia. If you try running 'kdesu nvidia-settings' or 'gksu nvidia-settings', then try to save with "Save to x confguration file" button, but receive the error:
Failed to parse existing X config file '/etc/X11/xorg.conf'
I found the problem by running:
sudo nvidia-settings 2>/dev/null

VALIDATION ERROR: Data incomplete in file /etc/X11/xorg.conf.
Undefined Device "(null)" referenced by Screen "Default Screen".

Erreur de segmentation
My default /etc/X11/xorg.conf looks like this:
Section "Screen"
Identifier "Default Screen"
DefaultDepth 24
EndSection

Section "Module"
Load "glx"
EndSection

Section "Device"
Identifier "Default Device"
Driver "nvidia"
Option "NoLogo" "True"
EndSection
To fix the problem, just remove the Section "Screen" part. IF YOU NEED HELP EDITING CONFIGURATION FILES UNDER LINUX, please see this link: http://awesomelinux.blogspot.com/2010/09/how-to-edit-configuration-file.html

The final version (before you edit it with the nvidia-settings program) should look like this:
Section "Module"
Load "glx"
EndSection

Section "Device"
Identifier "Default Device"
Driver "nvidia"
Option "NoLogo" "True"
EndSection

    This would be wonderful if I knew how to open XORG in order to change it! This shows what to do after one knows how to open it to begin with. Too new at this.

    You can open the xorg file from command line with:

    sudo nano /etc/X11/xorg.conf

    You will be prompted for your password first, since it requires admin privileges to edit.

    I also had an extra line in

    Section "Module"
    Load "glx"
    Disable "dri2"
    EndSection

    which worked after I changed it to:

    Section "Module"
    Load "glx"
    EndSection

    I still am experiencing some problems.

    First, it will not save to ?etc/X11/xconf.backup.

    Second, even though I can apply, I cannot get two separate screens. Clones is no good and when I try positions, seems to be one big screen. I have primary as 'absolute' and secondary as 'top'.

    I have tried left, right etc. but cannot get two separate screens.

    Any suggestions?!

    Thanks

      I am sorry I cannot help you with this. I am not experienced with this problem. I would suggest you ask for help on the Ubuntu forums.
