You will need to reboot afterward, but do the install first since you won't have a working GUI otherwise (before rebooting, the driver will still be in memory even though it is no longer on disk). yum remove all of those then try installing. This will give you a pretty straightforward list. Also, when using third-party drivers like Nvidias, you should learn the basics of the text-mode console. That should allow for upgrade with a minimum of fuss. So, I know you are frustrated BUT you would be better off putting more effort into the question - saying, 'I have spend hours trying just about everything I could find' without saying what you've tried will put people off, because they won't bother to suggest something that you've probably already tried. In other words, if you use Nvidia drivers packaged by RPMFusion on Fedora 35, you should delay updating to Fedora 36 until RPMFusion has known-working Nvidia drivers for Fedora 36 too.

The dark theme looks terrific, reduces strain on the eyes, and helps save the battery life of your devices, especially if youre. The out-of-the-box wallpapers also offer dark mode variants for a more cohesive user experience. A recent nouveau benchmark using ubuntu 12.10 seems to indicate nouveau still lags considerably behind the prop driver. Fedora 36 ships with an all-new dark mode which applies a dark theme to all applications that support this color scheme.

I did have access to an NVIDIA card at the time and the issue was much the same for that. My ati card is currently sitting in a box because I don't need it (or to waste wattage) but the last time I used it with linux ~4 years ago to do some openGL work, there was a very very substantial difference between the prop driver and the open source one, so you are probably not unjustified here.
