KDE + i3 - plasma hangs fairly often

So plasma seems to hang on me fairly often when using KDE + i3. KDE alone I was not able to trigger this, nor was I able to when using KDE + awesomewm. Tried KDE + bspwm and got the same behaviour.

Plasma would just stop, meaning no access the krunner and the panel would stop updating. Everything else would be running fine though, and `killall -9 plasmashell & kstart5 plasmashell` would get things working again.

It got annoying enough that I searched and found two other forum topics:-
https://bbs.archlinux.org/viewtopic.php?id=247874
https://bbs.archlinux.org/viewtopic.php … 3#p1854103

The recommendation for adding i915.enable_psr=0 to my grub boot line works. But this is from more than a year ago, with multiple kernel updates in between. If its a regression, how do I find out (this wasn't happening a month ago) and where do I report it to?

tl;dr he's on intel, complained about unreal, but QSGRenderThread blocked the GPU as well so my gut was at https://bbs.archlinux.org/viewtopic.php … 0#p1948920
The rest of the thread is about the wonders of git bisecting the kernel ;-)

Seems to be rather in plasmashell than in kwin and the compositor might mitigate it (do you run awesome along a compositor and i3/bspwm not?)

Maybe you can try to set kernel parameters with:

i915.enable_psr=0 intel_idle.max_cstate=1 i915.enable_dc=0

It didnt help me, but it can help you.

I found it here: https://linuxreviews.org/Intel_graphics

Interesting, I thought I was using picom in both, will test that more. Definitely not a kwin issue since I'm only getting it when replacing kwin with something else.

EDIT: Yep that was definitely it, my awesome rc.lua just wasn't starting picom, once I did the crash happened just the same. And the bootline fix works as well!
