How do I deactivate the X11 video device auto-settings?
Okay, time to move on to the next annoying problem with my machine.
I need to know if someone can tell me that will force X11 to default to
a specific display mode (24 bit color w/ 1024x768 resolution) when it
starts up. I am using an LCD display that is not very forgiving in
other graphic video modes and for some reason, even though I have that
listed as the only option in xorg.conf, it still switches to another
video mode when it first starts up. When I force a restart to the
Xserver, then and only then does it use the video mode I specified.
Some help here would be appreciated and here is the section of my config
file that contains the setting:

You *might* want to play with the DDC option in your xorg.conf, to stop
it probing your hardware for settings, so it just uses what you,
configure yourself.
e.g. Option "DDC" "off"
You can try reading the man files for your graphics chipset, e.g. "man
i810" (substituting whatever yours actually is), but I've found that
some of the options mentioned in these man files were completely
ignored.

Environment:
Fedora 8
xorg-x11-drv-nv-2.1.6-1.fc8
Nvidia NV34 [GeForce FX 5200] (rev a1) connected with
digital to analog converter (supplied by card vendor) to Compaq KVM
(don't know exact model) to (analog to analog) Dell FP2405FPW LCD monitor.
This solved my problem.
On FC4 everything was working properly.
On F8 i tried nvidia proprietary driver and it worked only in 1920x1080.
With nv driver and this setup i got 1920x1200 back again.
