Description sponix2ipfw 2024-08-01 14:06:31 UTC 
I had to switch over to sddm-x11 and load my plasma-x11 session. I was able to run the wayland version of sddm, and load a KDE Plasma 6.1.3 wayland session prior. Not sure if this is the Nvidia 560.28.03 Binary Driver causing this issue, but that seems most likely

Reproducible: Always

Steps to Reproduce:
1.try to load wayland sddm or a Plasma 6.1.3 wayland session and all I get is a black screen
2.toggle over to sddm-x11 and the Plasma X11 session then things load and work fine
3.
Actual Results:  
wayland sddm and Plasma sessions do not load. I only get a black screen. It also keeps me from using the keyboard commands to swap back to a text console.

Expected Results:  
I expect wayland sddm and the wayland Plasma sessions to load and work

Wayland is just a protocol specification in XML and the low-level C library that deals with the protocol.

This issue here is a bug not with the protocol itself but with either your compositor, driver or desktop environment's implementation of the Wayland protocol and surrounding functionality.

I believe this is probably a bug or incompatibility in the egl-wayland library that comes with the NVIDIA closed source driver.

Nothing to do with Wayland (the component).

Try downgrading the NVIDIA driver.

does this work with egl-wayland-1.1.15 and egl-gbm-1.1.2  installed? 

there is still an issue with egl-wayland-1.1.15-1, though.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 42 development cycle.
Changing version to 42.
