I was running Red Hat ELv3 and I upgraded to v4 since v3 is going unsupported.
The upgrade ends by rebooting the machine and now the X11 login screen won't
start. Apparently the gdmgreeter is failing. The primary visible symptom is
that as the boot sequence completes the text login appears, then the screen
goes from black to a muted background with circling dots in the center, which
is what would normally be followed by the login screen. Then it flashes, the
text login prompt reappers, and shortly thereafter the screen changes and gets
circling dots again.
If I log in to the machine using the text (non-graphic) login I can "startx"
and everything works just fine. I can run the system-config-display utility
and I've tried various screen size and depth variations. There are no obvious
error messages in /var/log/Xorg.0.log when using startx and none when gdm is
trying to start. The X11 server itself is apparently starting quite happily.
What is logged in /var/log/messages is just:

If I enable debugging in gdm.conf then there is more information written to
the system log but there is no indication of what is actually going wrong.

-------------------------------------
Does anyone know what this "failsafe dialog" is? Or what "inhibitions" are?
Is there perhaps a way to get gdmgreeter to log something useful?
Everything I've been able to find by way of Google is several years old and
usually hardware specific one way or another.
Any suggestions?
