powerprofilesctl says "Not Authorized"

Hello
I'm getting this when I try to set a different power profile on my laptop:

$ powerprofilesctl set power-saver
Failed to communicate with power-profiles-daemon: g-dbus-error-quark: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Not Authorized: org.freedesktop.UPower.PowerProfiles.switch-profile (9)

Doing it via sudo works

Does my user account need to be a member of a particular group (I've tried power)?

Trilby

You need to start / enable the daemon process first: https://wiki.archlinux.org/title/CPU_fr … les-daemon

Thanks for the suggestion but that doesn't seem to be it:

$ systemctl status power-profiles-daemon.service

Re: powerprofilesctl says "Not Authorized"

Is your dbus/loginctl session broken? How are you starting your session and which session are you starting?

loginctl session-status

Ah! That's it.  I get the error if I'm logged into the machine via ssh, but not when I'm using the machine directly.  Thanks for your help!
