You normally shouldn't need to do this. For user bus, the address is configured in dbus.socket; for session buses it is passed as command line option. <div class="gmail_quote"><div dir="ltr">On Sun, Oct 4, 2015, 21:40 arnaud gaboury <<a href="mailto:arnaud.gaboury@gmail.com">arnaud.gaboury@gmail.com</a>> wrote: </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">As I am trying to improve my knowledges in how dbus work, I discovered this file in /etc/dbus-1/session-local.conf ------------------------ <busconfig> <listen>unix:path=/run/user/1000/dbus/user_bus_socket</listen> </busconfig> -------------------------- I Can't remember editing it, but I must have done it. I understand it overrides settings in /usr/share/dbus-1/session.conf In my case, it is correct as my session dbus socket is indeed in the above path, thus override <listen>unix:tmpdir=/tmp</listen> in /usr/share/dbus-1/session.conf. Now I am wondering this: I am user 1000 and almost the only one user of the machine. But what if another user log in? In this case, the path will be somewhere else. Does this file recognize environment varaibles like ${XDG_RUNTIME_DIR } ?
