1. I assume by Command Line you mean GNOME Terminal?
2. I entered passwd at above and successfully changed it. Actually, I just swapped User passwords and I still do not have Root access to System Settings.
3. The Red Hat link describes Single-User Mode. It says the purpose is if you can boot successfully but not log-in. Well, I can log-in, so it doesn't seem this solution applies to me. If it does apply to me I don't understand the directions. I could be specific but I thnk I'll wait for a response to above. Thanks again.
