KDE install is completely FUBAR with nvidia driver

Important to note: Gnome works, and while it has issues can be completely fixed with this: Set default GPU on GNOME to use iGPU - #2 by simplycorbett

When installing the KDE version of Fedora 41 and then using RPMFusion and installing the following packages, the install completely bricks itself and is stuck on a black screen. I am not able to access any other TTY. SSH does not respond.

sudo dnf install akmod-nvidia
sudo dnf install xorg-x11-drv-nvidia-cuda

100% bricked on restart.

I have tested this on a laptop with intel iGPU+nvidia dedicated GPU and a 7950x desktop with a AMD iGPU and a nvidia dGPU.

What are the steps to get a working install with nvidia drivers on the KDE fedora install media?

Secure boot is not enabled.

Added f41, kde

What Nvidia cards you are using?

4

2070 super and 2080ti.

There isn’t too much on processa since no sec boot

After the RPM transaction ends, please remember to wait until the kmod has been built. This can take up to 5 minutes on some systems

Only I can for now thing reboot was faster than it could build modules

Restart after it can show drivers are really build

modinfo -F version nvidia

This might be the issue, then. But I don’t know how to recover the existing install?

I could do a livecd and then chroot, since the old kernel image isn’t working either. But this seems like something that should be more user-friendly IMO.

This might help

I did a full reinstall. I specifically watched top this time and waited until the kernel was finished rebuilding.

The entire install is still FUBAR. GRUB does not appear, I cannot change TTY, I cannot use SSH and the screen is blank.

I will stick with the gnome version of fedora since KDE is broken.

I removed rhgb quiet from GRUB via live cd, and surprise, the entire install works now with no other changes.

So maybe that option should be removed from fedora for nvidia users.

When there are issues with the nvidia driver you can always get into a system with ssh to investigate and fix. Many people are using KDE with nvidia without issue.

The fact that you cannot suggests that there is a deeper issue then nvidia drivers.
I wonder if there is a hardware issue that the KDE install is triggering that Gnome does not.

You might want to install memtest and run it overnight to check that you do not have an intermittent RAM problem.

It’s fixed by removing the “rhgb quiet” options from grub, so no reason to.

Nice debugging!

That suggests that the issue is with the plymouth splash screen.

Other people have seen issues with the splash screen not working as they required because of GPU driver issues, not restricted to nvidia.

Yes, but it’s interesting that this issue only happens with KDE and not Gnome.

Is plymouth specific to kde? I dont remember.

Plymouth is used on all fedora spins and editions.
Kde or gnome does not start until a long time after plymouth has started.
But the exact set of services maybe different and change the timing of the boot sequence.
