Hans de Goede dc48bd653c systemd-logind: Monitor systemd-logind going away 
When we're using server managed-fds through systemd-logind, systemd-logind
*must* keep running while we are using it, as it does things like drmSetMaster
and drmDropMaster for us on vt-switch.

On a systemd-logind restart, we cannot simply re-connect since we will then
get a different fd for the /dev/dri/card# node, and we've tied a lot of
state to the old fd. I've discussed this with the systemd people, and in the
future there may be a restart mechanism were systemd-logind passed fds from
the old logind to the new logind. But for now there answer is simply:
"Don't restart systemd-logind", and there never really is a good reason to
restart it.

So to ensure unpleasentness if people do decide to restart systemd-logind
anyways (or when it crashes), monitor logind going away and make this a fatal
error. This avoids getting a hard-hung machine on the next vt-switch and will
hopefully quickly educate users to not restart systemd-logind while they have
an X session using it active.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
following article:

All questions regarding this software should be directed at the
Xorg mailing list:

Please submit bug reports to the Xorg bugzilla:
