gnome-open raises this error when run from inside tmux

rated 0 times [ 5] [ 0] / answers: 1 / hits: 2774 / 3 Years ago, tue, october 26, 2021, 3:40:05

The error I get is this:

GConf Error: Failed to contact configuration server; the most common cause is a missing or misconfigured D-Bus session bus daemon. 

See http://projects.gnome.org/gconf/ for information. 

(Details -  1: Failed to get connection to session: Error connecting: Connection refused)

Failed to open bus: Failed to connect to socket /tmp/dbus-BYC0LHrEHk: Connection refused

Any suggestions?

Instead of letting Gnome run dbus-launch to create a random D-Bus address, start dbus-daemon explicitly early in your X session startup and give it a fixed address like unix:path=~/.dbus-$HOSTNAME-$DISPLAY.

Given the information in the bug report, you may even be able to get away with unset DBUS_SESSION_BUS_ADDRESS and let applications find out the bus address from the root window properties.

As of 15.10, the per-session dbus instance is created via an Upstart session job. The job file in question is /usr/share/upstart/sessions/dbus.conf. You can replace the default random address by overriding the pre-start script stanza which specifies the address to use. Create ~/.config/upstart/dbus.override with the following:

pre-start script

    DBUS_SESSION_BUS_ADDRESS=unix:path=$HOME/.dbus-$(hostname)-$(echo $DISPLAY | sed -e s/:/%3A/)

    initctl set-env DBUS_SESSION_BUS_ADDRESS=$DBUS_SESSION_BUS_ADDRESS

end script

The fixed address will be used after you next log in.
