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.

3. upower.service is enabled and running.

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!
