I just installed Fedora 7 and run into this problem when trying to log in as root afterwards. When I log in as root ,graphical, I get a black screen after a couple of seconds and and an error message. In the error message there is a tick box which lets me check a log file of some kind. The message reads: "root being added to access control list. No profile for user root found". I can log in as root in just text mood. Is there any way to fix this?
