hi!
i installed a new gentoo system and now i'm trying to setup sound according to the gentoo pipewire wiki. as root i have sound (except for firefox-bin but that's probably a different topic...).
when i try to configure my standard user by
Code:

systemctl --user disable --now pulseaudio.socket pulseaudio.service
systemctl --user enable --now pipewire-pulse.socket wireplumber.service
systemctl --user enable --now pipewire.service
systemctl status pipewire.service

i get
Code:

Failed to disable unit: Process org.freedesktop.systemd1 exited with status 1
Failed to enable unit: Process org.freedesktop.systemd1 exited with status 1
Failed to enable unit: Process org.freedesktop.systemd1 exited with status 1
Unit pipewire.service could not be found.

so, my user has somehow not enough rights to perform the systemctl commands.
what might i have missed? any group, my user needs to be part of? any systemd-setting activating multi-user...?
thanks a lot in advance!

Why are you using
Code:
systemctl status pipewire.service
and not
Code:
systemctl --user status pipewire.service
?

And for what needs the user "root" any sound?

you are right, the --user is missing on the last command, however that doesn't change anything:
Code:

systemctl --user disable --now pulseaudio.socket pulseaudio.service
systemctl --user enable --now pipewire-pulse.socket wireplumber.service
systemctl --user enable --now pipewire.service
systemctl --user status pipewire.service

yields executed as my standard (=non-root) user:
Code:

Failed to disable unit: Process org.freedesktop.systemd1 exited with status 1
Failed to enable unit: Process org.freedesktop.systemd1 exited with status 1
Failed to enable unit: Process org.freedesktop.systemd1 exited with status 1
Failed to get properties: Process org.freedesktop.systemd1 exited with status 1

and you are also perfectly right, root does not need sound. i am trying to activate sound for my standard user. yet, it seems i am missing sth since the systemctl commands do not succeed but exit with code 1.

what am I doing wrong? what further information should i provide to solve this?

Do you have the USE=dbus flag set?

As normal user
Code:
emerge --pretend --verbose media-video/pipewire
echo $DBUS_SESSION_BUS_ADDRESS
?

Yes, dbus USE-flag is set.
Code:
root ~ # emerge --pretend --verbose media-video/pipewire

Local copy of remote index is up-to-date and will be used.

These are the packages that would be merged, in order:

I just made another observation:
Code:
user ~ $ shutdown -h now
Call to PowerOff failed: Interactive authentication required.
user ~ 1 $


Usually, I can shutdown the computer as user.

In my opinion (I may be wrong): Your DBUS_SESSION_BUS_ADDRESS variable looks strange. Do you execute the dbus-launch command manually or in a script?

I would expect a value like "unix:path=/run/user/1000/bus" where the part "1000" is the same as "id -u" (the user id). But my expectations may be wrong.

Regarding the shutdown problem: This might be related to your PolicyKit configuration.

Dbus is launched during the boot process by systemd using the out of the box implementation and configuration, which I do not have modified.

I also think that somehow my standard user does not have the usual permissions compared to my former gentoo installations.

The shutdown problem seems not so much a surprise anymore regarding that
Code:
root /sbin # l | grep shutdown
lrwxrwxrwx   1 root root       9 18. Aug 14:57 shutdown -> systemctl*
root /sbin #

I also compared the groups my former standard users where members of with no differences.

What could be wrong with PolicyKit? I never configured it or worked with it consciously.

Another strange effect: my standard user has ctrl+alt+backspace disabled, i.e. that combination does not restart my Xorg server.

Per this (possibly unrelated) bug report, maybe try downgrading from version sys-auth/polkit-124-r1 to version sys-auth/polkit-123 (if that applies to you)? Both are available.

The `dbus` service launches the system bus. This is not the same as a D-Bus session bus. This is a frequent point of misunderstanding, which is why i added the following to the 'D-Bus' page on the wiki:

Quote:
There are two distinct D-Bus buses: the system bus and the session bus. The system bus is for messages related to the system as a whole, e.g. hardware connects and disconnects. The session bus, on the other hand, is for messages related to a specific user session, e.g. an X or Wayland session. The dbus service provided by OpenRC and systemd only provides the system bus, not a session bus.

A D-Bus session bus can be started in multiple ways, e.g. via dbus-daemon(1) (which, in my setup, i call from my ~/.zlogin script), dbus-run-session(1) or dbus-launch(1). Some GUIs will take care of this for you; for others, such as window managers like Sway, one needs manually specify that a session bus needs to created, by starting the WM via the session bus creation command (e.g. `dbus-run-session sway`).

Indeed, the value described by drbrezner looks fine, and is a standard style of value. For example, my current DBUS_SESSION_BUS_ADDRESS is:
Code:
unix:path=/tmp/dbus-S8bVC2lyFo,guid=34199760089bcce9e45faf7566cb0dd1

That was the problem! Thanks a lot for pointing that out. Now the "systemct --user ..." stuff works without error. Thanks a lot!
