Post-edit: I moved these packages to updates repos.
Basically adding copy and paste commands to what @AngryPenguin posted. I think the current Lx 4.1 packages were built for kernel 5.5.4 and you would need to be logged in to that kernel to install these.
I think this would work:
$ sudo dnf install nvidia-440 --enablerepo rock-updates-x86_64-non-free
or
For some older nvdia hardware there is also nvidia-390 package.
$ sudo dnf install nvidia-390 --enablerepo rock-updates-x86_64-non-free
We need for @Colin to announce these and explain how they work. As I understood from watching them testing these user should just install these and reboot.
