For me X11 just flat out doesn’t work, fucks up the icons and scaling. Unusable.

After searching for it, I think it makes perfect sense since fedora people switched to TuneD in Fedora 41 and that’s what I was running.

It has been since like 2022 at least for me. I was on X11 and it looked blurry as hell. Same thing on wayland. One day, out of the blue a KDE update dropped and boom everything was crisp and clear. I thank the lords of wayland everyday 🛐. Since then, it has only gotten better

Switching to tuneD worked! Thank you so much!

Here’s what I did, from here. I’ve slightly modified the commands since that guide is from when tuneD was still on the AUR.

1. Uninstall power-profiles-daemon

sudo pacman -Rns power-profiles-daemon

2. Check that power-profiles-daemon.service is gone

systemctl status power-profiles-daemon

The output should be : Unit power-profiles-daemon.service could not be found.

3. Install tuneD:

sudo pacman -S tuned

4. Enable and start tuneD:

systemctl enable tuned
systemctl start tuned

5. Check that tuneD is running correctly:

● tuned.service - Dynamic System Tuning Daemon
     Loaded: loaded (/usr/lib/systemd/system/tuned.service; enabled; preset: disabled)
     Active: active (running) ....

6. Check the active profile:

tuned-adm active

Now, you can use tuned-adm to switch to profiles, but since I am using a DE, I won’t be doing that. Now reboot and the power profile slider should be working!

You could check if powerdevil is installed, also the applet won’t re-check if the requirements are fulfilled so you have to restart plasma and maybe even the whole PC

Obviously powerdevil is installed, hence the service, unless I am getting something wrong. I have restarted multiple times.
