I’m using Ubuntu, so in order to enable `dbus.service` I need to install `dbus-user-session`. After that I could run my the `activity-monitor` but the DBUS_SESSION_BUS_ADDRESS on the systemd process and the one I got on a terminal are very different. So the systemd process is not aware about the activity events.

DBUS_SESSION_BUS_ADDRESS inside the systemd process is `/run/user/$UID/bus` and on the terminal is something like `/tmp/dbus-RxW9pceAsk,guid=1d3ae57411c17ecacf1e3fa55e9e94e5`

I’m sure it’s an ubuntu / debian related problem but I don’t know how to act.
