Wayland with Hybrid Graphics, Multi-monitor on KDE neon 6.0

jaanonim · April 5, 2024, 1:23pm

Hi,

I’m trying to switch to Wayland from X11. My problem is that when I start Wayland, I get a black screen with a cursor (apps launched during autostart start normally - a window appears).

Checking:

$ sudo cat /sys/module/nvidia_drm/parameters/modeset
Y

and libnvidia-egl-wayland1 is installed on my system.

Operating system: KDE Neon 6.0
I use a laptop: IdeaPad Gaming 3 15ACH6, it has integrated graphics and an nvdia rtx3050 card. I want to use it as I have it right now, so when I’m not running games or anything demanding, it will use the integrated GPU. I have installed proprietary nvidia drivers 535.161.07. I also use a secondary monitor (the secondary and primary monitors on this laptop are connected to the integrated graphics).
I’ve read that Wayland is getting better, but is it good enough to meet these needs?

(I looked for this information but it’s mostly Arch fixes, but I may be missing something, if so please point it out to me)

Thank you for all your help.

Plasmashell is crashing apparently.

Can you share the result of the command in a terminal:

coredumpctl -1 info plasmashell

Thanks for so fast replay .

coredumpctl -1 info plasmashell dosen’t found anything from plasmashell.

Only thing that shows up in coredumpctl is /usr/lib/x86_64-linux-gnu/libexec/kf6/baloo_file but that seems unrelated because it happends also with X11.

I run ournalctl /usr/bin/plasmashell -n 1000 --no-pager.

It looks like it migth be related to: 1.1.12 regression: can not run glmark2-es2-wayland with prime render offload · Issue #83 · NVIDIA/egl-wayland · GitHub .
I don’t realy know for witch packet version to look… I cheked libnvidia-egl-wayland1 is in version 1:1.1.9-1.1 but it look like it’s the newest availbe on mi system.

coredumpctl -1 gdb plasmashell then, it should download the necessary debug symbols, you will need to let the process continue (type c or enter when it pauses) until you get a line starting with (gdb) then the trace should be useful

jaanonim · April 26, 2024, 7:46pm

@meven
Running coredumpctl -1 gdb plasmashell give me No match found..

meven · April 27, 2024, 10:23am

Maybe try instead coredumpctl -1 gdb kwin_wayland

coredumpctl without any parameter will tell you what traces are available.

coredumpctl -1 the last one.

jaanonim · April 28, 2024, 11:10am

There are no coredumps.

$ coredumpctl
