If you are running F35 and the nVidia drivers from rpmFusion be careful before you update the nVidia drivers. The nVidia drivers update to 495 drops support for some GPUs.  But the update doesn't check for that.  So, you may end up with a system with a broken GUI desktop.  In my case, I was able to get the login screen sometimes, but it would hang with the 495 driver. I reverted to the 470 driver and all is fine. FWIW, the nouveau driver also causes hangs with my GPU.  I'd buy a new version of GPU but nVidia is hard to find at the moment.
