My laptop does support this feature since it was working on Fedora KDE. But jumping over to arch, it seems not to work at all.

1. power-profiles-daemon.service is enabled and running.

2. plasma-powerdevil.service is static and running.

3. upower.service is enabled and running.

● upower.service - Daemon for power management
     Loaded: loaded (/usr/lib/systemd/system/upower.service; enabled; preset: disabled)
     Active: active (running) since <time>; 12min ago

             └─540 /usr/lib/upowerd

I’ve already tried to to put

GRUB_CMDLINE_LINUX_DEFAULT="amd_pstate=active"

as a kernel argument that doesn’t seem to do anything as well. I can’t figure it out. The power management settings work tho. Any idea what’s wrong? Thanks.

      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!

    Thanks for posting the update. I had a bunch of trouble with that when using arch on my thinkpad.

    I later switched to Fedora with plasma as I could not get video acceleration to work in Firefox.

    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.
