I made the change but it did not work. Allow me to provide more details about what I am doing.
I have a test diagnostic deployed in F14 GNOME. I am hoping to migrate to F15 KDE but I have to satisfy a primary requirement which is to automatically log in as root and not wait for the operator to log in to minimize delays in the test operation. So I am experimenting to see how to configure for this requirement.
Logging in as root is blocked in Fedora for the obvious security reasons. There are a number of guides on how to allow it. A search should bring up more than you need.
