Re: unable to access GUI by root login in fedora 9

That's normal behavior for Fedora 9.

Direct root logins to the GUI desktop have been disabled to discourage bad administration habits.

If you're the only user of the system *AND* the system is not and will not be connected to the Internet in any way, it *might* be reasonable to re-enable GUI root logins.

If you've used to always using root for everything, it most likely means you haven't really learned how to use user groups, file permissions and sudo effectively. You should set up your system so that you can do as much as possible of your "normal work" with your regular, personal user account.

If your system is under a strict auditability requirement (like bank or credit card company systems), then it is an *absolute requirement* that all important system changes can be reliably associated to a named person: "who-did-what". In such an environment, "just quickly logging in as root to fix this" gets the company into trouble with the auditors, and eventually gets you fired.

If every Unix/Linux sysadmin would learn to do things the right way by default, then the future sysadmins in security-sensitive locations would hopefully be less likely to make any stupid security mistakes.



If you still want to do it, you should learn how the authenticatin system works. If you know that, re-enabling root logins can be done easily in less than two minutes.

Google this: "PAM configuration".
