Subject: [PATCH] Honor initial setup being disabled by distro installer
Sysadmins might want to disable any kind of initial setup for their
users, perhaps because they pre-configure their environments. We
already provide a configuration file option for this but distro
installers might have their own way of requesting this.
At least the anaconda installer provides an option to skip any kind
post-install setup tools so, for now we're only adding support for
that but more might be added in the future.

Subject: [PATCH] display: Handle failure before display registration
Normally, e.g., gdm-wayland-session would register its display
before starting the session. This display registration is how
the display moves to the "managed" state. We currently detect
session failure in gdm_display_unmanage. If gdm-wayland-session
is killed before it registers the display, gdm_display_unmanage
won't run, and failure won't be detected.
This commit make gdm_display_unmanage get called, even if the
display isn't yet fully managed.

Subject: [PATCH] local-display-factory: pause for a few seconds before falling
back to X
logind currently gets confused if a session is started immediately as
one is shutting down.
Workaround this problem by adding an artificial delay when falling
back to X.

Subject: [PATCH 2/3] gdm-x-session: run session bus on non-seat0 seats
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 3/5] daemon: save os-release in accountsservice
It can be useful to know what OS a user was running
when they logged in (to detect upgrades).
This commit saves that information in accountsservice.

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.

RHEL 7 users need to stay on X if they were using X,
and they need to stay on gnome-classic if they were using
gnome-classic.
This commit examines the user's config to deduce whether
or not they were using RHEL 7 and in the event they were
try to get the right settings.

Subject: [PATCH 5/5] daemon: fix wayland detection when deciding to bypass
Xsession
At the moment if there's a session file with the same name in
both /usr/share/xsessions and /usr/share/wayland-sessions, GDM
will think the wayland is getting used when deciding whether or
not to bypass the /etc/gdm/Xsession script, even if wayland is
explicitly being ignored.
This commit fixes the check.
