Switching user with "su" does not count as opening a full new session (see /etc/pam.d/su). This does not start a session bus and systemd process in particular.

I have `systemd --user` always running for the user by running `loginctl enable-linger user` I've confirmed the `systemd --user` instance is running as that user using `ps` but when I try to run any `systemctl` command as that user, I get the following error: vagrant-ubuntu-vivid-64:~$ systemctl --user list-units Failed to get D-Bus connection: Connection refused Based on my googling it sounds like I should have a `dbus-daemon` instance running as that user but it is not. It should be noted I'm switching to the user with `su` so it may not be counting as a "login". It seems that either: 1. My user instance of `systemd` should use the system instance of d-bus. 2. Ubuntu should somehow be starting a user instance of d-bus. On Gentoo, for example, there is a user instance of `dbus-daemon`.
