Hi Nick.m, I have the same laptop. First, I tried the first option (install catalyst) but didn't solve my problem.

I solved the problem using the second, but It was no simple. First I tried to change the boot options, adding the argument i915.enable_ips=0 to GRUB_CMDLINE_LINUX on in /etc/default/grub but it does not work after run grub2-mkconfig -o /boot/grub2/grub.cfg.

It was because I have UEFI boot. Grubx64.efi uses EFI/fedora/grub.cfg in your UEFI file system. Then, in order to update that file you should run sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg.

You can test it running sudo cat /boot/efi/EFI/fedora/grub.cfg or in grub menu you press "e" and should view the i915.enable_ips=0 argument in linuxefi invocation.
