1. Does X start correctly when you enter 'startx' from the command line????
If not, the runlevel config may be incorrect.

2. Have you tried booting to runlevel 3, then starting X to see if it 
will start there????

If X will start from runlevel 3 but not at boot from runlevel 5 then 
suspect some differences in the config in the /etc/rc.d/rc(3-5).d contents.

If X will not start in either runlevel then suspect a network 
configuration issue.


I have included at the bottom a copy of the listing of my 
/etc/rc.d/rc5.d and /etc/rc.d/rc3.d contents for the processes that are 
started/stopped when booting/switching to runlevel 5 or 3.

My system boots to runlevel 5 nicely and I have no problems at all.
This is the same setup I had on RH 7.2, and it carried over to RH 7.3

NOTE.  If your network is not properly configured, the xfs server will 
not start correctly. If the xfs server is not running X will be unable 
to start because it relies on network config to contact and communicate 
with the  xfs font server in order to start.
      network config includes loopback interface, nic, and the 
/etc/hosts file properly set up for your system. The /etc/hosts file 
MUST have the line for the localhost with the loopback address 
(127.0.0.1) and should have lines for any other ip address on the local 
system. Without the localhost entry X !!!!WILL FAIL!!!!.
      it also includes the /etc/host.conf file which should probably 
include the line 'order hosts, bind' so the system is looking for the 
configuration in the hosts file before it tries DNS.

No, you need to fix the X configuration. Runlevel 5 tries to start X if 
everything else is properly configured and should work if the xfs server 
is running correctly and the network is configured correctly

As yet you have never told us if X will start properly from the command 
line. THIS IS THE FIRST STEP.  Get X to run from the command line, then 
do the graphical boot. If X does not run from the command line you 
cannot expect it torun at boot.

NOTE: to change runlevel configs you can manually change the links in 
the /etc/rc.d/rc?.d directories.  A listing beginning with K will make 
sure this process is stopped (Killed) when entering the runlevel and one 
beginning with an S will be (Started) when entering the runlevel.
There are other tools for this, but I use the command line mostly.

I remember the runlevel editor on the start menu in RH 7.2 but had to 
look for it in RH 7.3
I found it by logging in as root, starting X, then opening the 'Start 
Here' window from the task bar (or desktop) icon.  It is the tool 
labeled 'service configuration' and does not show up when logged in as a 
regular user.

It is a graphical tool and is not available from the command line unless 
X is running.
