SUMMARY *** When logging into wayland session, plasma will fail to start. I get a black screen and the applications I had open. Trying to open krunner from a konsole also fails with "wayland protocol error". See attachment for an excerpt from journalctl with logs from kwin and plasmashell *** STEPS TO REPRODUCE 1. Log into wayland session OBSERVED RESULT There's no plasmashell, and can't launch anything related to kde except for Dolphin, which shows up without any icons. EXPECTED RESULT System functional, as it is under Xorg SOFTWARE/OS VERSIONS Linux/KDE Plasma: 6.0.0 (available in About System) KDE Plasma Version: 6.0.0 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 ADDITIONAL INFORMATION Distro: KDE Neon Laptop ThinkPad P1 Gen 4i. GPU: NVIDIA GeForce RTX 3080 Laptop GPU Optimus, profile "on demand", but fails equally under always nvidia Nvidia driver: 550.54.14, but same result under 545 and 540 Kernel 6.7.6-x64v4-xanmod1 Extra note: I've had this exact behavior with kde5 as well, it basically never worked.

Some additional information, when under the broken wayland session, this is what happens if I try to launch krunner from a konsole: warning: queue 0x5857bcff4c70 destroyed while proxies still attached: wl_registry@37 still attached kf.svg: The theme "Adapta" uses the legacy metadata.desktop.

I'm on a desktop with nvidia. The desktop is unusable in wayland (see attachement on how it looks like and it also flicks when moving any windows) but I believe I should add the following info: If I have a previously x11 session which gets restored, applications like konsole, kate and even firefox seem to have no issues. I believe the issue is related to applications which I think (please forgive my ignorance here, it's been some time since I messed with the plasma source code) are based on kirigami (???) or qml (???) I mean stuff like systemsettings, discover, elisa and spectacle (these are the apps I tried). When I launch these through konsole, I get the same error as reported by the other user warning: queue 0x5857bcff4c70 destroyed while proxies still attached: wl_registry@37 still attached The number of the queue changes each time but the " wl_registry@37 still attached" is always the same. Hope that it helps. PS: Thanks for your efforts! :)

Apparently my issue was the dual nvidia GPU. I have a workstation with an RTX5000 and an RTX2000. If I remove either of these wayland works perfectly. I'll create another bug report.
I'm having the same issue, tried nvidia drivers 535, 545, 550 with NVIDIA GeForce GTX 1650 and enabled/disabled "on demand" in nvidia-settings.

That sounds like your install is broken; are you sure you have the latest updates from Neon? Also, does it work on a different distro?

Yeah, I'm afraid we can't do anything about that. Please report this to NVidia at https://forums.developer.nvidia.com/c/gpu-graphics/linux/148
(In reply to Zamundaaa from comment #15) > Yeah, I'm afraid we can't do anything about that.

@Nicolas > What exactly should one report there? Just this error message? Is it universally understandable? Just describe your problem, any logs/error messages and also point them to this bug report. You need also to provide them the file that is generated if you run sudo nvidia-bug-report.sh They will ask you if they need any further details.
Some people have reported [1] that an upgrade of egl-wayland helped them, would it be possible to provide newer packages of egl-wayland on neon, instead of 1.1.9? Upstream is 1.1.13. [1]https://github.com/NVIDIA/egl-wayland/issues/61
manually upgrading to egl-wayland 1.13 fixed the problem for me
