I came this commit hash to terwiz[m] on IRC, who is trying to figure out
what the last version of Spectrum that worked on their NUC with Nvidia
graphics is.

+  <title>User Sessions</title>
+  <para>
+    Systemd keeps track of all users who are logged into the system
+    (e.g. on a virtual console or remotely via SSH). The command
+    <literal>loginctl</literal> allows querying and manipulating user
+    sessions. For instance, to list all user sessions:
+  </para>
+  <programlisting>
+$ loginctl
+   SESSION        UID USER             SEAT
+        c1        500 eelco            seat0
+        c3          0 root             seat0
+        c4        500 alice
+</programlisting>
+  <para>
+    This shows that two users are logged in locally, while another is
+    logged in remotely. (<quote>Seats</quote> are essentially the
+    combinations of displays and input devices attached to the system;
+    usually, there is only one seat.) To get information about a
+    session:
+  </para>
+  <programlisting>
+$ loginctl session-status c3
+c3 - root (0)
+           Since: Tue, 2013-01-08 01:17:56 CET; 4min 42s ago
+          Leader: 2536 (login)
+            Seat: seat0; vc3
+             TTY: /dev/tty3
+         Service: login; type tty; class user
+           State: online
+          CGroup: name=systemd:/user/root/c3
+                  ├─ 2536 /nix/store/10mn4xip9n7y9bxqwnsx7xwx2v2g34xn-shadow-4.1.5.1/bin/login --

+</programlisting>
+  <para>
+    This shows that the user is logged in on virtual console 3. It also
+    lists the processes belonging to this session. Since systemd keeps
+    track of this, you can terminate a session in a way that ensures
+    that all the session’s processes are gone:
+  </para>
+  <programlisting>
+# loginctl terminate-session c3
+</programlisting>
