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.

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.

    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.
