Xorg.conf different in SUSE 11 to Live CD

[t.web]

Hi,

whilst getting to the bottom of some display issues I addressing in the following forum

http://www.linuxforums.org/forum/sus...e-drivers.html

I had cause to complare my xorg.conf file from my installed v 11 to the one on the liveCD and was startled at the difference. As my problem relates to 1 of my 2 graphics cards (a VGA Geforce 2 MX 400), and whilst I play about with the Geforce driver which doesnt want to install, I was interested to work out why KDE happily loads on the monitor with the Geforce card when I used the liveCD.

When running the Live CD it had at least picked up my old Maxtor PCI graphics card as there where entries in the liveCD xorg.conf 's device section for it, this file was a few pages long. This compared to the SUSE 11 installed version where the xorg.conf contains less than a page of info. I was wondering could anyone explain why this difference would occur?

Monitor section from xorg.conf file on my live CD (why do I not find similar created on my installed version)

Section "Monitor"
DisplaySize 376 301
HorizSync 30-83

ModelName "MD30919PO C12"
Option "DPMS"
Option "PreferredMode" "1280x1024"
VendorName "MED"
VertRefresh 43-75
UseModes "Modes[0]"
EndSection

Needless to say I've taken the one from liveCD and copied it onto my harddrive for the moment.

Xorg tries to run dynamically now, as in it doesn't create permanent configurations in xorg.conf the way it used to. It uses EDID to guess the monitor configuration. This also helps when you switch monitor.

I guess that SUSE is configuring xorg.conf in YaST for you during the full installation and creating a permanent xorg.conf. So I guess if YaST was getting it wrong it might work out better to have a more minimal approach in xorg.conf and let the X server figure the rest out.

thanks for the response, I didn't appreciate X server as it served out graphical tasks to GUI etc (assuming I understand that right) could function independantly of xorg.conf. Now I know and it explains a lot. Thanks again
