Two monitors in Redhat Tikanga 5.6 - X Server Fails

Hello friends,

I am not very familiar with Redhat or Linux in general.

I am trying to get two monitors to run on a government computer that came pre-loaded with Redhat 5.6 ... I had no input into the version. When I follow instructions here:

(The best I could find for my version) it tells me I need to log out, fine. I do and nothing ever comes back. A blue screen error comes up that says "Failed to start the X server (your grapical interface). It is likely that it is not set up correctly. Would you like to view the X server output to diagnose the problem?" So the only way to get the desktop back is to go back to the one monitor setup. I have tried different resolutions and have tried "generic" vs. my actual monitor type.

Any ideas on how to resolve this issue?

Thank you for your help.

Is this a computer you are using at work ?
one you got used from a gov. office and are using at home

i ask because RHEL 5.6 is a bit old , and red hat is not a free operating system
You need to have a paid license and register it with red hat
RHEL5.8 is the current in the old 5 series
If this computer has not been upgraded to 5.8( form 5.6) then it has not received any SECURITY updates in over a year.
( With the exception of back porting them to the old 5.6 - and that is not cheep )

if this is a box you are using in a govt. office your tech support / your system admin will have the needed info

if not ?????

you might not be able to install any needed software needed to fix this .

Some information on the hardware will help
"" is a good start if you have no idea what is in the computer

it is an interactive shell script for normal basic linux commands
You will need to be root to run it

using two monitors normally needs a 3d card ( and the driver )

option "5" in the script lists the PCI devices
one of them is the video
or use the terminal
su -
lspci | grep VGA
and that will output the graphics card/ chip if there is one
