Bug 481986

journalctl excerpt

Some additional information, when under the broken wayland session, this is what happens if I try to launch krunner from a konsole:

[destroyed object]: error 7: importing the supplied dmabufs failed
The Wayland connection experienced a fatal error: Protocol error

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! :)

> [destroyed object]: error 7: importing the supplied dmabufs failed

this one is relevant. it means that krunner can't create a graphics buffer so the compositor could display it. Not sure why nvidia would refuse to import a graphics buffer. If your laptop has an intel gpu, try switching to it instead.

Both had no icons, and system info had 0 information, no entries at all.

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?

As sure as a fresh install from KDE Neon provides, and that my current install works fine under Xorg.

> Also, does it work on a different distro?

Testing on a different distro is something that I can't do right now, sadly.

As said, "[destroyed object]: error 7: importing the supplied dmabufs failed" indicates the the same issue

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

What exactly should one report there? Just this error message? Is it universally understandable?

Though I didnt try wayland often, I remember that it kind of worked before with kde 5..

@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
