Among the many new features planned for Ubuntu 26.10 is switching the default D-Bus implementation over to using the high performance Dbus-Broker drop-in replacement.
Seven years after Fedora 30 switched over to Dbus-Broker for its default D-Bus implementation, Ubuntu Linux is achieving the same with Ubuntu 26.10. Ubuntu developer Alessandro Astone posted today about the Dbus-Broker plans for Ubuntu 26.10 for this implementation providing not only better performance but greater reliability and scalability.
The post notes the delay in Ubuntu switching over to Dbus-Broker has been held up by GNOME’s GDM relying on dbus-run-session provided by the dbus-daemon package and it only being reworked in GNOME 49 to avoid that dependency. And due to Ubuntu’s AppArmor integration as well as Snaps there was handling needed there as well.
Canonical’s plan is to move the dbus-broker package to main for Ubuntu 26.10 and have it installed and enabled by default. Dbus and Dbus-Daemon will be moved down to universe.
Those wanting to learn more about the Dbus-Broker plans for Ubuntu 26.10 can do so via the Ubuntu Discourse.
The switch to Dbus-Broker is coming as a new Rust-based BUS1 in-kernel IPC mechanism recently entered the spotlight in looking toward the future.
