Greeter Error

[Bob Chiodini <robert chiodini-1 ksc nasa gov>]

Good Morning,

I noticed this morning a problem with gdm-slave-greeter. The following
message appears in /var/log/messages:

Apr 12 07:13:08 solaria gdm[2176]: gdm_slave_greeter: Cannot start greeter trying default: /usr/libexec/gdmlogin

Selinux is in permissive mode.  A dialog appears on the screen titled
"Configuration is not correct" and says the following:

"The configuration file contains an invalid command line for the login
dialog, so running the default command.  Please fix your configuration."

What configuration file is this referring to?

Bob...
