KDE interactions freeze entire system


I’m not really sure how to troubleshoot this issue further since there doesn’t seem to be anything that pops up in journalctl.

I’m on the latest arch kernel but this has been happening for a few versions.

I’m on the stock KDE that comes with the EOS install. The only real config I’ve changed is moving the taskbar to the top of the screen.

So whenever I interact with the taskbar - clicking the application launcher or any of the widgets on my taskbar, the entire system freezes for ~10 seconds and my laptop fans start spinning. Also some graphical glitches happen, this is what the application launcher looks like after it finally opens up. Any ideas?

I’m assuming you tested this on the lts kernel already with the same results?

Running Zen-kernel with Plasma on EOS.
Sorry to confirm this issues, I thought it was my fault or my hardware’s.
The last 3 days my system froze constantly, had to hard reset it quite a few times.
This never happened before, and my system is perfectly fine, as hardware parts, which I troubleshoot and tested.
Something about KDE or an update causes it, I didn¡t had the time to look at the system logs.

You really shouldn’t do that, you’re just risking filesystem corruption. Consider enabling the Magic SysRq Key to be able to reboot safely in any situation:

This is concerning if true. Fortunately, it does not seem to be universal.

I really don’t understand how people have all these issues. I have not had one issue with Plasma on EOS yet. It has to be hardware related or adding in other stuff like widgets, or other global themes and or other software etc.

If you are running stock EOS please post your hardware. Is it Intel graphics? You say you’re running stock but i see a round orange circle which tells me changes have been made.

LTS kernel doesn’t work with my wireless card so it’s a no-go regardless.

It is Intel. The orange circle is my initials that show up in the app launcher, probably just looks weird because of the graphical glitch. The only changes I made are moving the taskbar to the top of the screen, which is to me still stock since I’m just changing some of the basic settings that KDE provides. I did have latte-dock but I removed it and the issue still persists.

(it’s currently running linux-next-git kernel but the same issue happens in the latest EOS provided kernel)

Have you tried removing the intel driver. xf86-video-intel

Edit: You can also try i915.enable_psr=0 as a kernel parameter in the default grub command line and the update grub.

Looks like a bug introduced in kernel 5.15. I don’t really have time to test it but either downgrading to 5.14 or applying the patch linked below to 5.15 should resolve the issue.
