After I login to kde I get display artifacts.
Distro : Fedora 39
Hw : Dell G15 5515 (Laptop)
GPU : AMD + Nvidia optimus
Try these instructions Howto/Optimus - RPM Fusion
I have already done these instructions. Nvidia drivers and optimus was working fine before this bug.
What changed between it all working and now?
New kernel? Did you wait for the nvidia drivers to be built?
No, it’s a clean install. And it was already up to date before the bug happened.
I did change the refresh rate to 60hz. It was 120Hz before. This is a freesync display. VRR is off in settings.
You will need to provide some details please.

What happens if you do sudo dnf reinstall \*nvidia\*
There are packages that get installed by default that are missing or extra in that list.
xorg-x11-drv-nvidia-libs.i686 & xorg-x11-drv-nvidia-cuda-libs.i686 are both missing and
libva-nvidia-driver is extra (not included) for a default installation of the nvidia drivers from rpmfusion.
It reinstalled the existing packages. Did not install new packages.
I removed the home directory and created new one. Plasma worked fine, so it’s definitely a config issue. Any way to find what the problem is ?
Maybe settings related to “variable refresh rate” and “refresh rate” ? I did change those settings before this issue happened. I also changed the power profile to battery in the last working boot.
Continued here since the issue is more specific now.
