You are not supposed to use the GUI as root. Never required.

So root login is disabled. For security reasons.

As knudfl pointed out, there is no issue to 'solve'. It's disabled for security reasons, because it is ALWAYS A VERY BAD IDEA TO LOG IN AS ROOT, PERIOD. There is NO REASON to do it, EVER, unless you're in single-user mode, trying to fix a very serious problem.

Read the LQ Rules about text-speak, and about not using it. It's "please", not "pls".

Also, since you're using RHEL, you are PAYING for RHEL...RIGHT???? Have you called them for support/assistance? Did you try to look this up on the Red Hat website, which you're paying for access to?

edit /etc/gdm/gdm.conf
in [security], add :
AllowRoot=true
save file and restart gdm

Warning:
if you login as root into the gui login
you can and WILL have all kinds of unexpected problems
that basically are not easily solvable

--- DO NOT LOG IN TO THE GUI AS ROOT !!! ---

see "TB0ne's" above post!!!!!!
