Multiple problems in Fedora 38

One issue that many see is lack of patience before they reboot.
Rebooting before the nvidia kernel modules have been completely compiled by akmods and installed can cause corruption and failure to properly load the drivers.

One easy fix is to (from the command line) do the following.

1. sudo dnf remove 'kmod-nvidia-*' which will remove all the currently built modules (for all kernels).
2. sudo akmods --force which will rebuild and reinstall the modules for all the currently available kernels.
3. Wait until the prompt returns then wait another minute or so for certainty that all has been completed.
4. reboot

If you search this forum you will find many posts about similar problems and the fix for almost all has been either a removal and full new install of the drivers or rebuilding the modules as shown above.

Just as an aside, related to signing the kernel modules on fedora.
The instructions at rpmfusion are much more compact and to the point than the linked tutorial.
Even better is to do dnf install akmods then follow in detail the instructions in the file /usr/share/doc/akmods/README.secureboot before installing the packages from rpmfusion.

The simplest and most complete way to install the drivers from rpmfusion is to enable the rpmfusion repo then dnf install akmod-nvidia xorg-x11-drv-nvidia-cuda which will pull in as dependencies all those extra needed packages that are verbosely listed and not entirely correct in the tutorial linked.

It worked for me, issue closed
