DBus session bus address is not properly set

ShionjiYuuko · 2016-12-31 01:58:21

I've been trying PulseAudio equalizer qpaeq. It fails to launch with error

There was an error connecting to pulseaudio, please make sure you have the pulseaudio dbus module loaded, exiting...

Module equalizer sink and module dbus protocol is activated in /etc/pulse/default.pa

Tracing the error gives reveals that the cause is environment variable $DBUS_SESSION_BUS_ADDRESS being empty. Setting it manually to /run/user/$UID/dbus/user_bus_socket gives error

org.freedesktop.DBus.Error.ServiceUnknown: The name org.PulseAudio1 was not provided by any .service files

Result from systemctl --show-environment

DISPLAY=:0
HOME=/home/uname

LC_COLLATE=C
LOGNAME=uname

USER=uname
XAUTHORITY=/home/uname/.Xauthority
XDG_RUNTIME_DIR=/run/user/1000

For login I'm using lightdm and awesome WM.

There's should be something wrong in the login.
How can I set the environment correctly? I've been checking all xinit files but there seems to be nothing that rewrites environment variables.

Thanks

General_troubleshooting#Session_permissions
Also is DBUS_SESSION_BUS_ADDRESS still unset if you log directly into a terminal instead of through lightdm?
Also what is the output of

$ systemctl status --user dbus.service

I had a similar problem a while ago, and whilst I didn't trace it back to a specific setting, I fixed it by:

moving ~/.config to ~/.config.bak

This resulted in $DBUS_SESSION_BUS_ADDRESS being correctly set. Then I moved files from the .bak directory into the new .config as required.

https://bbs.archlinux.org/viewtopic.php … 3#p1662433 refers.

- The local session is valid
- DBUS_SESSION_BUS_ADDRESS is unset in terminal
- dbus.service status

What is /etc/systemd/user/dbus.service? That should not exist.

Hi! As the OP I can't open qpaeq and throws the same message.

Anybody can help me?

This is wrong. Find where you're using dbus-launch and get rid of it.

Removed the file, but $DBUS_SESSION_BUS_ADDRESS still empty.

On my single user 4x Archlinux installs echo $DBUS_SESSION_BUS_ADDRESS shows

DBUS_SESSION_BUS_ADDRESS=/run/user/1000/bus

see if that helps, as mentioned

/tmp/dbus-iDskgvL60r,guid=aaaa474d48be6e7fc55dbc43588e34f3

looks wrong.

Check to see if you have the same file somewhere under ~/.local/share/systemd. I did (don't know how it got there), removed it, and everything is good.

EDIT: I believe that it was under ~/.config/systemd and not ~/.local.

Same problem with dbus. Some programs can not be started (gnome-terminal) or can not save settings (meld) because of error "dbus-launch: Autolaunch requested, but X11 support not compiled in". I tried all advice I found with no luck.

$ loginctl show-session $XDG_SESSION_ID | sort

$ systemctl status --user dbus.service
Failed to connect to bus: No such file or directory

Also I tried to move ~/.config to ~/.config.bk, reboot system, restore it back and reboot again - no luck.

I read these topics:

General_troubleshooting#Session_permissions
D-Bus#Starting_the_user_session
/news/d-bus-now-launches-user-buses/

The only one interesting thing I found:

First, make sure you have a valid local session within X:
$ loginctl show-session $XDG_SESSION_ID
This should contain Remote=no and Active=yes in the output. If it does not, make sure that X runs on the same tty where the login occurred. This is required in order to preserve the logind session.

But I do not understand what does it mean: "make sure that X runs on the same tty where the login occurred"? How can I check that? Here is my process list, maybe it could help:

I use nodm and fluxbox. Here are my configs:

NODM_MIN_SESSION_TIME=60
NODM_RESTART_SESSION=0
NODM_XINIT='/usr/bin/xinit'

~/.xinitrc:

#!/bin/bash
exec xbindkeys &
exec xxkb &
setxkbmap -layout "us,ru" -option "grp:caps_toggle,terminate:ctrl_alt_bksp"
exec startfluxbox

~/.fluxbox/startup:

#!/bin/sh
slock
exec fluxbox

My colleague have been using lightdm and Cinnamon and they work flawlessly.

I almost lost hope to fix that problem. Please give me advice, I will provide any information needed.

No, you don't.
Don't use nodm but autologin with getty - see eg. https://bbs.archlinux.org/viewtopic.php?id=220954

vimusov,

It has been reported that your post is a thread hijack. I tend to agree. Please start a new thread and, if you believe this thread to be relevant, you may link back to this one.

I am sorry about that. I thought it would be better to not start a new topic when there is an existing one with the same problem. I am going to do as you say.
