To use the proprietary Nvidia drivers you have to downgrade the X
server to 1.17 (F23 supplies 1.18):

sudo dnf --showduplicates --allowerasing --releasever=22 downgrade xorg-x11-server-Xorg

You can then install the Nvidia 353.55 driver package from Nvidia's
site. I did this recently and haven't had a freeze since.
