Plz check if u have a file name gdm.conf , usually Ubuntu have , not sure in Fedora , if there , its a conf file , where u can see variable named AllowRoot , to true , which will satisfy ur need .
But normally not used coz of security reasons ,plz set to false after ur need
mine is in /etc/gdm/gdm.conf , i'll show some part of it
# Allow root to login. It makes sense to turn this off for kiosk use, when
# you want to minimize the possibility of break in.
AllowRoot=false ------ set to true will make u happy
