That is odd.  Try running gdmsetup, and turning on debug by checking
the checkbox in the Security tab.  Then restart gdm by running
gdm-restart as root (this will cause any running sessions to exit
so don't run it with unsaved data in your running session).

Then share with us the "gdm" related messages that get sent to
your syslog (/var/adm/messages or /var/log/messages) file.  This
will probably highlight the problem.

Normally when the greeter restarts, it is because there was a crash.
Is there a core file in your root (/) directory, or in /var/lib/gdm
or /var/lib/log/gdm?  Sometimes gdm will leave core files here that
we can check for a stacktrace.
