FastX: Gnome Screen Saver Lock

Problem

FastX displays a black screen, login window, or screen saver as a screen shot in the session manager.
When a user resumes their gnome session, they have to enter their password again to display the desktop.

This occurs when the screen saver is enabled in gnome.

Solution

Disable the screen save in Gnome.

Gnome 3 (RHEL 7)

The following are instructions from Gnome on changing the settings for their screen saver. Please note the first few steps asks to create certain files. These files may already exist on your Red Hat 7 host.
