I use FC3 and after running "yum update" I cannot login as root using the GUI , I get the message "root cannot login". If I login as a regular user there is no problem.
I modified the /etc/inittab changing the runlevel from 5 to 3, rebooted then I can login as root in text mode and then execute the command "startx" so I can use kde as root.
tia for any tip, advise or suggestion
