[SOLVED}Problem with some services not functioning

Hello
This is related to this.

I thought it is totally solved but I spoke too soon!

Just to be exact "dbus launch" causes the issue with running mpDris2 through xinitrc.
None of them was the cause of mpDris2 not functioning through its user service!

I have tested with these three services so far and they function as a new instance but not as service. (playerctld, mpd-mpris, mpDris2(These there are --user services.))
I checked their status while running but nothing was there to help me.
These are the running services and I believe they're functioning as they should!

What could possibly be the cause??

I think those are user services, right? So they would not be listed in the system services. Add the "--user" flag:

https://wiki.archlinux.org/title/Systemd/User

EDIT: nevermind - you noted in your post that these indeed are user services and you even mentioned the "--user" flag. But the command output you showed did not include the --user flag. So what's the question??

That running services list will be for the system bus, rerun those with --user to get the user bus.

As you can see playerctld is running but it doesn't function and if I run a new instance of playerctld it function as it should

What do you mean it "doesn't function". That's not an error message. And is it actually running? Can you find it with `pgrep`?

The service file might need to be adjusted. Honestly, I'm not sure of the best practices for service files for traditional daemons that fork themselves as playerctld seems to do ("modern" trends seem to discourage this behavior). Personally I'd just launch these from xinitrc directly (as one would do for urxvtd or similar traditional daemon processes).

Well playerctld should detect latest player that its status is changed!
The service can't do it and I should run a new instance of playerctld for it to work.(detect latest player)

I guess this is something related to playerctl because all these services I'm trying to run try to utilize playerctl
For example "playerctl -l" shows no output with mpd-mpris as service
But If I run a new instance of mpd-mpris through terminal "playerctl -l" shows "mpd"
How I deducted it's playerctl issue?
Well look at this

[best8oy@DIAMOND ~]$ systemctl --user status mpd-mpris.service

It shows mpd-mpris is actually connected to mpd (detecting volume changes) but playerctl is unable to detect it(mpd)!

As for playerctld, it seems to be broken; it's running but why is it saying finished tracking?

[best8oy@DIAMOND ~]$ systemctl --user status playerctld

     Loaded: loaded (/usr/lib/systemd/user/playerctld.service; enabled; preset: enabled)

[best8oy@DIAMOND ~]$ pgrep playerctld

The normal output of playerctld should be like this

[best8oy@DIAMOND ~]$ playerctld

(playerctld:222066): playerctl-WARNING **: 17:50:51.355: could not get properties for active player: GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: No such interface ?org.mpris.MediaPlayer2.TrackList?

I guess just adding them to my xinitrc is the way to go! No headache!

BEST8OY · 2024-04-17 15:49:20

I have to add
When running "playerctld daemon" it works as it should (detect the latest player) (it shows as /usr/bin/playerctld with parent:systemd and user:best8oy in "btop")

But when I have a oneshot service for playerctld (ExecStart=/usr/bin/playerctld daemon) and it shows the exact same information in "btop" but playerctld doesn't seem to work!

I'm so confused about the reason!
