@TJ1 The power-profiles-daemon is not Fedora-only. I believe it comes Out of the box with Fedora re-spins (will be standard with Fedora 35)
https://fedoraproject.org/wiki/Changes/Power_Profiles_Daemon
and some of the latest Ubuntu Releases.
I know some packages exist for Arch as well.
https://security.archlinux.org/package/power-profiles-daemon
If I recall the daemon originally started as a project targeting Linux systems that were running the standard GNOME desktop,
The power-profiles-daemon project was created to help provide a solution for
two separate use cases, for desktops, laptops, and other devices running a
“traditional Linux desktop”
but KDE/Plasma started support for it fairly recently as well.
I believe I’ve seen some other posts mentioning people running it with other Linux OS’s like NIX, I’ll reply with them linked if I find them again.
