Bug filed: https://bugzilla.rpmfusion.org/show_bug.cgi?id=5307

The driver itself seems perfectly fine in that the system boots and OpenGL works perfectly fine. Games are playable.

How do I output strace to a file directly? It spits out way too much info.

The bug is reproducible by doing a fresh install on a new downloaded ISO but really the likelihood that this is a bug caused by Nvidia is slim to none. Arch Linux(what I primarily use) has the same driver version and everything works perfectly fine.

Regardless of whether or not this specific bug was by a packaging issue or Nvidia, the way Fedora packages the Nvidia drivers is bad:

-nvidia-smi isn't specific to CUDA and is a core Nvidia library interface that should come with the base driver as it does in Windows.
-nvidia-settings is the Linux alternative to Window's control panel and if not included by default, *should* be included via a "meta" package for desktop users.
-OpenGL not packaged with the driver(or again, installable via a meta package)? Who wants a graphics driver without OpenGL/Vulkan support?
-it isn't clear if the command I posted(above) installs the 32-bit libraries or not. Really, meta packages would go a long way in simplifying GPU driver installs!

Neither Windows nor even other Linux distros fragment the driver this much. You'd have to add 32-bit libraries alongside the 64 bit driver and 64 bit libraries to equal Fedora's fragmented driver packaging in some distros. Why?

Not yet, you need to provide more useful info as stated in the RPM Fusion wiki
https://rpmfusion.org/Howto/NVIDIA#Bug_Report

Once we can determine the driver is in good state, a strace log of
nvidia-settings would be useful.
Please report to bugzilla.rpmfusion.org for now, but if it's
reproducible and not related to packaging, you will have to forward to
nvidia directly.

Thx
