deleted xorg.conf system-config-display wont work

I deleted my xorg.conf and all backups. Tried to run system-config-display and all I get is my monitor flashes 5 or 6 different colors constantly. If I run system-config-display --reconfig it will just sit there with a black screen.

I thought system-config-display would generate a new file? How can I get x working again?

Ok I ran system-config-display --noui -v --reconfig and it did create an xorg.conf file but it lacks a monitor section. When I try to run system-config-display again it displays a screen but it's purple with white slanted dot's and I cna't make it out at all.

I ran X -configure and it generate an x config file in root's home dir. I think tried to restart gdm but it said something aobut the PID not existing. When I follow the advice of trying to test the configuration file in root's home dir I get the same result, screen flahes 6 different colors, white, blue, red, etc.

I switched the driver of the video card in xorg.conf from nv to vesa and it's now back up and running.

Reinstalled the nvidia driver, back at the same problem of my dell 1900fp being detected as a samsung with a max resolution of 1024x768; Never had more of a problem with anything in linux before, this is driving me crazy.

Just ignore the detected monitor. Go into system-config-display, go to hardware and configure and choose generic display 1280x1024 or whatever your monitor supports. Press <Ctl><Alt>Backspace and if you're lucky you will see a login screen. You may have to comment out or remove the section in xorg.conf where it looks like this:

Section "Monitor"
Identifier "Monitor0"
ModelName "LCD Panel 1400x1050"
# HorizSync 31.5 - 65.5 # commented out
# VertRefresh 56.0 - 65.0 # commented out
Option "dpms"
EndSection

My screen is 1400x1050 so change that to whatever.

When I go into system---config---display it refuses to save the changes, when you press OK it just sits there. When ran from terminal it says

File "/usr/share/system-config-display/xConfigDialog.py", line 186, in ok
display_option = second_screen.display[0]
IndexError: index out-of-bounds


I believe the EDID information the Nvidia driver is getting it totally wrong. The problem is I don't know how to force it to display the resolution I want. No resolution above 1024x768 is available in the nvidia settings control panel. I think there is a way to disable EDID for just one monitor and supply 'modelines' but I dont' know how to do it. Frankly have screwed up X so many times that I'm not willing to experiment (we are talking hours here). I just need to know what to do exactly.

I really hate the Nvidia driver.

Hello;
If you want to bypass / disable the EDID with the nVidia drivers and default to what you have configured in your /etc/X11/xorg.conf file
then add the option to your
Section "Device"
Option "UseEDID" "FALSE"

Then reboot or restart your Xserver and see how it goes.
If you are still having problems then boot into runlevel 3 and then startx with
startx -- -logverbose 6
then check your /var/log/Xorg.0.log for the details as to why or why not certain modes were validated.

I have two Device sections and I added that change to each, now my 1900fp will only perform at 640x480. System config display still will not allow me to change the 1900fps properties.

Somehow your system-config-display got hosed. Something similar to this might fix it:

su
cd
yum clean all
yum update
yum -y install yum-utils
yumdownloader system-config-display
rpm -e system-config-display
rpm -ivh system-config-display
system-config-display

Same problem

Traceback (most recent call last):

display_option.modes[0].name = res
IndexError: index out-of-bounds

It simply wont allow to to change any of my second monitor's properties. I've tried disabling EDID information and used gtf to calculate a modeline but when I disable EDID info it defaults to 640x480
