Odd jitter on pc when watching videos or playing games

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

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

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.
