I have been able to get Prime Synchronization setup and working using drivers downloaded from www.nvidia.com and manually changing xorg.conf and Grub. I haven't been able to get this working on Ubuntu (not sure why) but I can get it working on Fedora (blasphemy!).
I've attached some files for research purposes. I'll try making a legit patch if I have time and can figure it out.
You'll notice nvidia- drm.modeset= 1 added on the command line Linux line
