Subject: [PATCH] data: reap gdm sessions on shutdown
If GDM gets shutdown we should make sure all sessions get shutdown too.
This is a bit of a safety net in case any processes in the session are
lingering after the orderly shutdown.

Subject: [PATCH] local-display-factory: Don't try to respawn displays on
shutdown
At the moment in the shutdown path we may try to respawn displays
that just got killed.
The respawning happens when things are half torn down leading to
crashes.
This commit makes sure we turn off the respawn logic in the shutdown
path.

Subject: [PATCH] session-worker: Set session_vt=0 out of pam uninitialization
MR GNOME/gdm!123 moved jump_to_vt and session_vt reseting to a
separate function, so we don't need to reset session_vt in pam
uninitialization.

XDMCP displays
The lower levels of GDM now expect the session types supported by a
display to be specified up front.
This commit makes sure XDMCP displays do that.

Subject: [PATCH 2/3] daemon: Don't update session type if no saved session
At the moment we always set the session type when the session name
is read. But users don't always have a session type specified.
If they don't, then don't set the session type.

GNOME doesn't deal very well with multiple sessions
running on a multiple seats at the moment.
Until that's fixed, ensure sessions run on auxillary
seats get their own session bus.

Subject: [PATCH 3/3] daemon: Infer session type from desktop file if user has
no saved session type
The accountsservice user cache file can specify a session type
associated with the saved session. This is optional though. If one
isn't specified GDM needs to figure out the session type based on the
list of preferred session types for the system and the session file
itself.
It was failing to do the latter, though. This commit fixes that.

Subject: [PATCH 3/3] session: ensure login screen over XDMCP connects to its
session
Right now GTK preferentially picks the wayland display over an
X11 display if it finds one.
That causes a problem for XDMCP sessions, since there may be a
wayland display running on the local console for the GDM user.
This commit addresses the issue by forcing the X11 backend if
the session is X11.
