Check your /etc/default/grub file, and make sure that "nomodeset" is not 
in it. I found this was in some of my /etc/default/grub files, because I 
had selected a basic text upgrade mode when running anaconda. This made 
the upgrades run faster, but it disabled the fancy graphics modes than 
gnome-shell needs.

If it is there, try removing the "nomodeset" clause and regenerate your 
grub files by running:

grub2-mkconfig -o /boot/grub2/grub.cfg
