Subject: blueman fails to find a dbus service file

Hello,

I'm not quite sure yet if this is a is an actual bug or a error on my
side.

Whenever I load blueman-applet, it will pop up an error saying:

    Failed to apply newtork settings

and

    g-dbus-error-quark:
    GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name
    org.blueman.Mechanism was not provided by any .service files (2)

Calling blueman-applet from the console gives:

--8<---------------cut here---------------start------------->8---
blueman-applet version 2.1.4 starting
Stale PID, overwriting
blueman-applet 22.15.06 WARNING  PluginManager:148 __load_plugin: Not loading PPPSupport because its conflict has higher priority

There is an instance already running

--8<---------------cut here---------------end--------------->8---

I just tried to get rid of this message by modifying my
%desktop-services with:

--8<---------------cut here---------------start------------->8---
(modify-services %desktop-services
                 (dbus config => (dbus-service #:services (list blueman))))
--8<---------------cut here---------------end--------------->8---

That worked, but it didn't help much.  After looking around online I
found that there has been an issue [1] reported on this before.  Looking
further from there [2] seems to be a viable solution, which is already
packed in the blueman package, but this file I can't find in the
system's profile.

Any help would be greatly appreciated.


Cheers,
Simon

Hello,


I had the exactly same problem, and this fixes it:

Those packages in system config:

                    "bluez-alsa"
                    "bluez"
                    "blueman"
                    "pulseaudio"


This service added

      (service bluetooth-service-type
          (bluetooth-configuration
              (auto-enable? #t)))


And this to modify-services

            (dbus-root-service-type config =>
                       (dbus-configuration (inherit config)
                                (services (list blueman))))

Better solution was suggested on IRC instead of modify-services:

(simple-service 'blueman dbus-root-service-type (list blueman))

It works for me. I had to run "PulseAudio volume control" or pulsemixer 
and select BT headpone as output.

I am not using Gnome. My config is basically i3 + xfce4.

Installed guix a few weeks ago on my desktop PC and just yesterday on my
laptop (thinkpad L13). Having the same problem on both of them.

Gnome's default bluetooth "app" doesn't work.

After having the same config as in your example I can launch
blueman-manager and connect to my bluetooth sound system. It makes a sound
as if it's connected and displays itself as connected but I can't pick it
as an output device in gnome's setting "sound" tab.

How have you dealt with this?

Bluetoothctl also works. So the problem is not bluetooth itself but it's
"connection" with audio in gnome's default way.

I eventually solved my problem by adding
--8<---------------cut here---------------start------------->8---
(simple-service 'dbus-extras
                dbus-root-service-type
                (list blueman))
--8<---------------cut here---------------end--------------->8---
to service list, and loading
--8<---------------cut here---------------start------------->8---
(gnu packages networking)
--8<---------------cut here---------------end--------------->8---
to load blueman in the declaration.

Will close this bug report since it is not deemed to be one.


Kind regards
Simon
