lost my display on redhat enterprise linux Es ver 3 !!!!!!!!!!!!!!!!!!!!!!!!!!

hi!  I tried to install red hat enterprise linux  on a hp proliant dl 585 with a flat panel monitor using Gui mode.  I failed to install this because the screen went blank with some message saying something about the resolution not being supported.  So I  used a CRT monitor and I could now use the GUI mode to set up linux.  
Now after I finished installing linux, when I tried to connect the flat screen monitor to the server I did not get anthing thing on the screen but the same message saying that the resolution was not compatible.  I once again connected the CRT monitor and tried changing the resolution to the lowest possible settings and when I restarted the server the display went blank. Now I am stuck.  I can only access the commad line.  How do i restore my setting back so that I can use my CRT monitor and even better use my flat screen monitor!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Check your /etc/X11/xorg.conf file.

In the section "Monitor", make sure the refresh rates are properly setup to fit your lcd display. My settings for a LCD Laptop are as follows (They should usually use the same values):

HorizSync                 31.5 - 48.5
VertRefresh              40.0 - 70.0

As pointed out by Rindi, /etc/X11/xorg.conf is the configuration file for your monitor, keyboard, mouse, graphics card. You can find lots of documentation about what goes in this file at http://www.xfree86.org.
Anyway, when you makes changes to your monitor setup via the Red Hat GUI configuration tools, Red Hat makes a backup copy of your Xorg.conf file. So providing you haven't kept tinkering and tinkering then a simple ove command will put he old config back.
$> mv ./Xorg.con.old ./Xorg.conf  
That will restore your settings, then follow Rindi instructions re getting the H and V sync's correct, look at the technical specifications on the back of the Flat Panel TFT they usual indicate the refresh rates.

If all else faile then you can re-run Xconfigurator which will assist in providing you with a default setup, There are some recently released patches from red hat, check out https://rhn.redhat.com/errata/RHEA-2003-194.html for further info

Hope this Helps

Well guys,
I sorted this out myself.  First of all I think in red had the config file is  /etc/X11/X86Config and not Xorg.conf.  I don't know if i am wrong, but I couldn't find xorg.conf.    Luckily for me there was another server of the same kind in another office with the same flat screen display.  I copied the x86Config file and restored it in this server and all was fine.
I tried running Xconfigurator before and it did not run for some reason. I have done a complete installation of Red had linux and I don't know why some of the commands don't run.
Anyway I don't know if I am to part with my precesious points cause the problem was sorted out myself.  
Thanks for all your help
Ask for a PAQ/Refund.
I think it is reasonable to PAQ this and refund the points, which I will do.
