saving changes to xorg.conf file; resetting after logoff


Hi all,

OS: OpenSuSe 10.3 on X86_64 with Quadro 4000 Graphics processor

Problem: i made changes to X server display configuration under NVIDIA X server settings and saved changes to X config file by clicking on "Save to X configuration file" and restarted X to make changes take effect. Everything works fine. But when i logoff and login (or login as another user), the changes are lost and one of the two monitors lost its resolution.

How to make changes to xorg.conf file saved ?

Please help me with this.
Thank you!

Below is the xorg.conf file when everything is good

Code:
 
more /etc/X11/xorg.conf

    EndSubSection
EndSection
And also i can see the difference between these two files below.
Code:
diff xorg.conf xorg.conf.06052012Err
71d70
<     Option         "TwinViewXineramaInfoOrder" "DFP-0"
But not sure how to make changes be saved across reboot/logoff

Just guessing.....

I have not needed to diddle with xorg.conf lately---it it possible that SUSE is using some other config file (and using the info to alter xorg.conf)?
