Odd jitter on pc when watching videos or playing games

[Noroc]

This happened recently maybe about a few days ago after I did a general yay update of all components.

I am a bit unsure where to look at whats causing the issue, but one cold lead is the power management settings.

I get the following message.

 When I try to start the service with

---

sudo systemctl start power-manager.service

---

---

---

I have powerdevil installed

I am running the following.

It seems it is a bug in ddcutil. See this post:

Anyone else have an issue in the last 48 hours with Power Management

I had arch installed yesterday and after an update the kde power management is just continuously try to start and then crash. Warning in Power manager and all options greyed out. The powerdevil applet wasn’t loading after yesterdays pacman update, and the org_kde_powerdevil process kept crashing and restarting. Installed EOS in rather than Downgrade back to ddcutil-2.0.0-1 as I fancied a fresh install. Same issue presented itself. I tried other distros like Opensuse and no problems were pres…

I think the consensus seems to be to downgrade ddcutil to a previous version seems to fix the bug for now until a fixed version is out.

Looks like ddcutil 2.1.0-3 fixed the bug for some, yet somehow introduced the bug to other systems. Try version 2.1.0-2 may fix it or 2.1.0-1 ?

Thank you

I used the following command

sudo pacman -U file:///var/cache/pacman/pkg/ddcutil-2.0.0-1-x86_64.pkg.tar.zst

I think its fixed now.
