QuatschQuelle <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |FIXED Status|REPORTED |NEEDSINFO --- Comment #5 from QuatschQuelle <[email protected]> --- UPDATE: Even after a system reinstall, it still did not work. I read the logs and tried fixing it for the last few weeks for 2-3h every day. I now have a solution, as KWin does not start fast enough or something. How I fixed it: ``` sudo usermod -aG i2c $USER sudo usermod -aG video,i2c $USER sudo pacman -S ddcutil --overwrite "*" sudo modprobe i2c-dev mkdir -p ~/.config/environment.d echo "POWERDEVIL_NO_DDCUTIL=1" >> ~/.config/environment.d/powerdevil.conf systemctl --user daemon-reload ``` Create a script and put it in autostart/after login: ``` #!/bin/bash sleep 15 systemctl --user restart plasma-powerdevil.service ``` So I tried everything else to fix it. As I said, I even reinstalled Linux, but it just didn't work. I can't be the only one having this problem. What I think is the problem is NVIDIA and KWin. Here are some extra logs from when it does not work: ``` Jun 30 21:16:50 cachyos-x8664 systemd[1092]: Starting Powerdevil...
