Help me review dinit configuration

Hi, I have configured pipewire and wireplumber to run as user level services but I see some errors in the logs and if I exit the X session and restart it, wireplumber doesn't work without restarting the service (I am using Xlibre + i3).

I have used these dinit configuration files:

Most of these error messages are harmless, they're essentially esoteric ways of saying optional dependencies weren't found.

Only thing that's related to your issue here are Failed to connect to the session bus and DBus connection closed. Your user services assume there's a user-level DBus outside dinit they can talk to, but this isn't always true; on your setup (in general, when a DBus user service is absent), user-level DBus is spawned by X11 in a random address, and when X11 exits (and DBus alongside it), they're left in a sort of limbo they can only leave by restarting and finding where the new X11 has placed the new DBus.

Either bring those dinit services down with X11 too, or make a DBus service. The latter, however, requires some knowledge on how D-Bus works to make it work properly with your other services. I'd recommend sticking with the distribution-provided dbus-dinit-user wireplumber-dinit pipewire-dinit pipewire-pulse-dinit, they deal with the nitty-gritty needed to survive the GUI session stopping.

Just create and enable this user service instead of your dbus-user-check:
Code: [Select]
type = process
command = /usr/bin/dbus-daemon --session --nofork --address unix:path=$XDG_RUNTIME_DIR/bus
smooth-recovery = true

This file is not as good as than the packaged one.

  • It doesn't wait for dbus-daemon to notify it is ready
  • It doesn't export DBUS_SESSION_BUS_ADDRESS to other dinit user services
  • smooth-recovery shouldn't be set to true because, as we can see through this user's report, when dbus-daemon crashes stuff that uses it should be restarted.

I installed the dbus-dinit-user as suggested and enabled it then I replaced on the wireplumber configuration the line
depends-on = user-dbus-check to depends-on = dbus.

It is working now when I restart X session. Thanks!
