Summary of the discussion: the issue is fixed by adding nouveau.modeset=0 to the Linux boot options. Try it by changing GRUB_CMDLINE_LINUX in /etc/default/grub and run `grub2-mkconfig -o /boot/grub2/grub.cfg` (see https://fedoraproject.org/wiki/GRUB_2 for more info).
 
If you're doing EFI booting and not BIOS then that would be /boot/efi/EFI/fedora/grub.cfg, correct?
 
Thanks,
