This is guide, howto install NVIDIA proprietary drivers on Fedora 32/31/30/29/28 and disable Nouveau driver. This guide works with GeForce 6/7/8/9/200/300/400/500/600/700/800/900/10/20/30 series cards. I have tested this guide with NVIDIA 340.xx (patched), 390.xx (patched), 440.xx, 450.xx and 455.xx drivers/cards on latest Fedora. Here I use NVIDIA 455.28 version, check full install commands from: https://www.if-not-true-then-false.com/2015/fedora-nvidia-guide/
