It's solved. I had to start `dbus-daemon --system` (/etc/init.d/dbus start). Would be nice if this would have been documented somewhere in gentoo's bluetooth guide (http://www.gentoo.org/doc/en/bluetooth-guide.xml). I'd appreciate it if you could suggest the maintainer of the document to make an addition. Thanks.
Jakub, please advise.
(In reply to comment #2) > Jakub, please advise. Hmmm? :) I don't think the description in comment #1 is correct. Looks like dbus was running already - but you need to reload the configuration or restart if after installing stuff that installs its own dbus configuration files/services etc. (see the ECONNREFUSED error). If you think that dbus should pick up the config changes on-the-fly via inotify or whatever, then you need to bug gentopia folks or preferably dbus upstream, not KDE. ;)
/etc/X11/xinit/xinitrc.d/30-dbus is executed when I start X. Hence, the following processes run without starting dbus via /etc/init.d/dbus start: /usr/bin/dbus-launch --sh-syntax --exit-with-session /usr/bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session Only when I start /etc/init.d/dbus start the error does not occur on my system.
