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
Comment 1 Olivier Fourdan 2024-08-01 14:14:45 UTC 
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.
Comment 6 Fedora Release Engineering 2026-05-06 11:52:23 UTC 
This message is a reminder that Fedora Linux 42 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 42 on 2026-05-13.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '42'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 42 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.
