well the very FIRST thing you need to do is read the nvidia install guide on fedoraforum
there is a ton more things that need to be done than just shout down x11
" telinit 3 " should still work with systemD
relogin as ROOT
------- i put it on "/" --------------
chmod +x NVIDIA*.run
and DO NOT forget to rebuild the boot image !!!!
the last thing on the fedora guide is 3 separate commands
and the last is using "dracut"
using the kmod-nvidia or the BETTER YET ( for the new user ) akmod-nvidia rpm is RECOMMENDED !!!!!
