With Ubuntu 16.10 developers are finally finishing their migration to systemd by switching over the starting of graphical desktop sessions from Upstart to systemd.

Ubuntu developers are planning to land more conversions of services of the Ubuntu session to making using of systemd. These packages have begun landing in the Yakkety Yak repository. But Kubuntu, Lubuntu, and others haven't yet seen their desktop sessions converted over to systemd.

Ubuntu users wanting to learn more about pushing desktop sessions from Upstart to systemd in time for the Ubuntu 16.10 release in October, see today's mailing list post by Martin Pitt.
