Rick Gatewood@ graphics ppa work for me, you can try. If you face back screen boot, then restart to recovery console:
mount -o remount,rw /
prime-select intel
If it don not work
apt-get purge nvidia*
If it work, login to desktop add graphic ppa address as @Alberto Milone.
On additional driver, choose Nvidia 364.19 (open source).
This work for me, PRIME profile work with both Intel and Nvida
