(solved)norm cpu usage for kwin under wayland failed wayland session?

Fullsteam · 2024-02-23 22:53:08

Hi there

I recently setup plasma under wayland and have been noticing CPU usage hitting 15 - 20% reported as coming from Plasma shell/kwin (according to Htop) also some cpu spikes from applications like chrome to 50% with light load is this normal
also while Wayland works fine with some graphical glitchiness apparently it opens a second wayland plasma session on tty2 with just a black screen and cursor

Ah, what?? There is no "Wayland" binary to run or be reported in htop. Do you mean plasma? Or what?

Yeah sorry trilby you're right plasma shell/kwin

Are you running in software on the llvmpipe device? Post

qdbus org.kde.KWin /KWin org.kde.KWin.supportInformation

do you have any cpu/resource monitoring widgets/plasmoids active? They've historically been the casue for higher CPU usage, might want to disable those

I noticed opengl platform listed as EGL i'm thinking like eglstreams as opposed to GBM which i have enforced through the enviroment variable is this a problem?
Also i'm not sure about many monitoring tools i have one on my desktop for individual core usage but nothing else.

also sometimes when i click on my start menu or the menu for things like vaults and other utilities not on the default bar the menus won't pop up

I admit i'm partly just going have i set this up correctly because the setup guides i found are quite small and i'm not sure if there is more i need to do beyond what they say.
setup Guides being

Thank you for all help on this

Yep and apparently sddm i think it is opening 2 plasma tty sessions and then when sddm is restarted it stops the failed? session on tty2 but leaves a broken session on tty1 i think
don't know if thats normal

seth · 2024-02-24 07:59:40

kwin doesnt support eglstreams and neither are you using that nor llvmpipe

also sometimes when i click on my start menu or the menu for things like vaults and other utilities not on the default bar the menus won't pop up

If you want to try plasma on wayland you likely want to go w/ the kde-unstable version - or wait.

apparently sddm i think it is opening 2 plasma tty sessions and then…

SDDM doesn't "think" - please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855

Apologies for the late response on this i suppose i'm used to running on a much tighter performance budget on a 3600x so i spooked when i saw core usage spike to 100%
In regards to the failed plasma session (black screen with just a cursor) which is the same thing i got when running egl streams not gdm it appears its because sddm will launch that session but its a placeholder? or fails? so when sddm is restarted the second screen on tty1 with a successful session will not shutdown.

On the basis of what Seth said i want stability so i transitioned back to xorg for the time being i hope to use wayland more in the future as its awesome.

Thank you very much to everyone who helped me in this thread
