It is hard to say.  In general, it is probably best to uninstall the
previous version of GDM before installing a new version.

Each distro has its own unique configuration for modules like GDM, so
problems could be related to how GDM was configured, or how your distro
integrates with GDM.  For example, if the system assumes that GDM is
installed to a particular file location, you may have problems if you
have installed it to a different place.  Also, each distro may apply
distro-specific patches to GDM, and it may not work without applying
such patches.  If you find it is not working, then it might be a good
idea to check with your distro and make sure that you apply any patches
needed for GDM to operate well on your platform.

You could try editing your /etc/gdm/custom.conf file so it contains
these lines:

[debug]
Enable=true

This will cause GDM to append debug messages to your syslog (the
/var/log/messages file )Then cause GDM to fail again.  After it fails,
you can check the gdm-related messages at the bottom of the syslog
file and see if it helps you understand why it might be failing.
You can share such debug output with us on this mailing list, and
we can help analyze the debug output if it isn't clear what the
problem is.
