Power Profile not working on Arch with KDE. Tried everything.

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.

    
● power-profiles-daemon.service - Power Profiles daemon

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

     Active: active (running) since <time>; 12min ago

             └─1074 /usr/lib/org_kde_powerdevil

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

     CGroup: /system.slice/upower.service
             └─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.

Installing tuned-ppd (I think I’ve got that right) fixes this for a lot of people
- 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!
  
  TuneD is really cool, but a weird fix for that problem.
  The lack of TuneD is one of the few things keeping me on Fedora and away from NixOS
  
  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.
  
  Yes I use it too, and tuned-ppd is very restricted but ensures easy compatibility
