How to list all active sessions in Gnome shell

Question

(System: Ubuntu 17.04 x64, official Gnome flavor, GNOME Shell 3.24.2 Wayland)

I have been experimenting with Gnome Shell extensions and some of them cause the session to crash. I have noticed that sometimes just a new session is generated as processes from the previous session are still active (using ps).

Question: What is the command to view all Gnome sessions?

(Follow up question) Is there a way to dump the current session and 'join' another active session?

yes, I tried poking around the documentation for `gnome-session` but no luck. — Erixun, Aug 16 '17 at 14:09
I actually found `loginctl list-sessions` is what I was after. There is also `loginctl activate [ID]` that has yet to work seamlessly, but I will keep tinkering with and STW for the correct process. — Erixun, Aug 16 '17 at 14:11
Perhaps you can post `loginctl list-sessions` as an answer, so the question is marked answered? :) — Lucas Werkmeister, Dec 23 '17 at 11:19

Gnome has a tool to manage concurrent sessions:

loginctl

This tool list sessions:

SESSION  UID USER  SEAT  TTY 
    173 1000 jehon seat0 tty2

1 sessions listed.

The tool also have a "kill session" utility:

loginctl terminate-session 173
