Public bug reported:
Since the beginning of time, the way to apply changes to one's group
memberships in UNIX has been to log out and log back in again.
In current Ubuntu, that doesn't work. When you add yourself to a group,
close all of your windows, log out, log back in again, and open a new
gnome-terminal window, and your group memberships will be the same as
before.
This is because gnome-terminal processes are launched by gnome-terminal-
server, which is launched by systemd --user, which doesn't exit when you
log out.
One possible fix would be to have the systemd init process (i.e.,
process 1) detect when group memberships have changed and re-launch the
systemd --user processes for the users whose groups have changed.
Another fix would be to kill systemd --user processes upon logout and
have systemd re-launch them.
