Recover from nvidia installation problems

My fedora 31 system running an NVIDIA GPU failed recently after partially running for several months. I was unable to find the problem source - it occurred when I rebooted and may have been triggered by a system update. Thanks for any help, I know this is messy.
My installation had used the rpmfusion howto and included cuda11.0. So I tried to uninstall nvidia and start over, again using the rpmfusion howto.

I find the GPU

bash-5.0# /sbin/lspci | grep -e VGA
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 620 (rev 07)
09:00.0 VGA compatible controller: NVIDIA Corporation GP107 [GeForce GTX 1050] (rev a1)
There is some evidence of the nvidia installation.
modinfo -F version nvidia
455.38
The kernel-devel modules are installed.
I disabled my epel repo since it seemed to have some conflicts with rpmfusion. My working repolist is

I can no longer install the akmod for nvidia.

A possible clue for why I’ve lost contact with the GTX1050 gpu is a message in /var/log/messages ( which only runs on shutdown)

Anything to be gained by upgrading to fed33?

First, you have, or at least had, the epel repo and the modular repos enabled so you have conflicting packages.

I would disable these repos

cernbox CERNBOX2.0 client repository (EOS backend)
eos-fc-30 fc-30 EOS release from EOS project
fedora-modular Fedora Modular 31 - x86_64
cuda cuda
google-chrome google-chrome
google-chrome-unstable google-chrome-unstable
updates-modular Fedora Modular 31 - x86_64 - Updates

then uninstall all nvidia related packages

 dnf erase '*nvidia*' 

finally reinstall all the nvidia packages from rpmfusion

dnf install akmod-nvidia nvidia* xorg-x11-drv-nvidia*

This will give you all matching and no conflicting packages for nvidia, including cuda for the nvidia card.
When you next reboot things should be normal.

Thanks for the detailed reply computersavy. I carefully went through your procedure.
First problem:

bash-5.0# dnf erase ‘nvidia
Error:
Problem: The operation would result in removing the following protected packages: kernel-core
(try to add ‘–skip-broken’ to skip uninstallable packages)
I’m worried that removing a protected kernel will brick my OS. Is this perhaps a kernel that gets recompiled for nvidia?
Proceeding anyway, second problem:
bash-5.0# dnf install akmod-nvidia nvidia* xorg-x11-drv-nvidia*

So the akmod failed. Wish me luck when I try to reboot!

Rebooting takes me to my original state of not accessing the nvidia gpu.

No xorg-x11-drv-nvidia which I believe is the required driver.
Any suggestions? It may be time to upgrade to fed33, but I’d like to fix this first.

What you displayed is not the same as I suggested for the removal step, and it seems you still have repos that are unneeded and conflicting that are active - especially the modular repos.
No, there is no special kernel for F31 and nvidia unless you have gotten it from the epel repo where part of your existing nvidia stuff was installed from. Epel repo is not fedora and often causes conflicts. Most people recommend to not use epel with fedora because of frequent version and dependency mismatches.

First, disable all repos except

fedora
fedora-updates
rpmfusion-free
rpmfusion-free-updates
rpmfusion-nonfree
rpmfusion-nonfree-updates

Limiting the number of repos enabled will help avoid conflicts and the others can be re-enabled later if you wish
Then do the removal of all existing nvidia packages, avoiding dependencies. You also need to remove all the currently installed cuda packages since installing the nvidia drivers from rpmfusion will also install the related cuda drivers.

dnf erase '*nvidia*' --noautoremove

Note the “*” on either side of “nvidia” which does not appear in your reply above (probably because the code tag at the beginning is not on its own line)

If this comes up with the kernel-core package you noted above, then do

 dnf disto-sync 

and reboot before trying again.

Then, still with only the six repos listed above, repeat the install using this command (modified from above).

dnf install akmod-nvidia nvidia* xorg-x11-drv-nvidia* kernel-devel kernel-headers 

This should fix the conflicts. If not you can address each one individually. Removing each epel8 package individually is almost a necessity if these steps do not clear it out. I notice that in the install list you showed several packages that did not come from rpmfusion. Nothing should be installed from anywhere but the main fedora repo or rpmfusion.

When the install is complete you should only have these nvidia related packages installed.

dnf list installed '*nvidia*'

You also will have one kmod-nvidia package that the system will build for you once the install is done. That is the actual nvidia driver module, custom built for your kernel.

I personally permanently disable the modular repos since I have seen conflicts with modular vs the regular fedora repos and your errors show similar…

After getting the nvidia drivers working I would suggest a full system upgrade with “dnf upgrade --refresh” while still using only the six above repos so that you know everything is up to date fedora wise. That will be needed anyway should you do a system upgrade to F33 later. As I am sure you are aware, F31 goes past EOL this month.

Thanks again, I appreciate all your experience. but still some problems.
I did disable the repos temporarily as you suggested. They were mostly apps for communicating with CERN.
I apologize for the overly detailed posting this time. Might be best to skip to the bottom and work back.

Current list is

dnf repolist
repo id repo name
fedora Fedora 31 - x86_64
rpmfusion-free RPM Fusion for Fedora 31 - Free
rpmfusion-free-updates RPM Fusion for Fedora 31 - Free - Updates
rpmfusion-nonfree-nvidia-driver RPM Fusion for Fedora 31 - Nonfree - NVIDIA Driver
updates Fedora 31 - x86_64 - Updates

I did the dnf distro-sync and removed all the epel packages that I found. They were mostly relics. Also removed the cuda-11.0 code in /usr/local that I had downloaded from nvidia as suggested in the rpmfusion howto. Perhaps this won’t be needed anymore?
I tried it first without the rpmfusion-nonfree-nvidia-driver repo, but the akmod was missing

This may be a change from fed 31 to fed32. Maybe upgrade to 32 and try again or go all the way to 33?
I don’t like the module filter messages I was getting.

I am not sure what is different there for you.
I have never used the

repo and have been using nvidia drivers from rpmfusion on fedora since at least F27 with no problems whatever.
In fact my current repolist is (and has been for some time)

The only thing I see causing the problem is the modular issue. Something was installed there that needs to be removed to eliminate the conflict. It is preventing the install of the xorg package and may be related to the nvidia-kmod-common package that is not used by F32. This site gives some instructions about modules in fedora 31.
Try removing nvidia-kmod-common then installing those packages you listed as missing.

If this doesn’t work we will have to try something else.

Yeah, that’s where I’ve been stuck. I can’t find nvidia-kmod-common or anything like it in the dnf listings

So not surprisingly dnf remove nvidia-kmod-common fails, and yet it stops me from loading the driver.
Even dnf autoremove and dnf distro-sync didn’t clear this problem.
Do you think upgrading to 32 or 33 might help? At least it is probably neutral. Or I could download the 455.38 driver from nvidia. The akmod-nvidia is still a problem then.
