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] 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] data: disable wayland on certain hardware
We're having issues with wayland on passthrough to virt
setups and with the vendor nvidia driver on hybrid graphics
setups, so disable it in those cases.
Also disable it on server chips for performance reasons.

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 1/3] 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: 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.

From 5a2d5dbdf8c6f6d3c896082a5a07b4292f5fb410 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/2] meson: set -D_GNU_SOURCE for updwtmpx
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Without setting GNU_SOURCE, we end up getting:
```
../gdm-42.0/daemon/gdm-session-record.c:200:9: error: implicit declaration of function ‘updwtmpx’; did you mean ‘updwtmp’? [-Werror=implicit-function-declaration]
updwtmpx (GDM_NEW_SESSION_RECORDS_FILE, &session_record);
```
This ended up exposing a bug in updwtmp(3) (which is now fixed
thanks to the man-pages maintainers!) as it didn't mention that updwtmpx
is a GNU extension (and hence needs GNU_SOURCE in order to be available).
Alternatively, we could just #define _GNU_SOURCE in gdm-session-record.c
for updwtmpx.
Bug: https://bugzilla.kernel.org/show_bug.cgi?id=216168

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.

Subject: [PATCH 2/2] daemon: Support X servers built with -Dlisten_tcp=true
Xorg since version 1.17 doesn't listen to tcp sockets by default
unless it's explicitly built with -Dlisten_tcp=true.
GDM currently assumes X servers 1.17 and later are always built
without specifying -Dlisten_tcp=true and doesn't work properly
otherwise.
This commit enhances GDM to better handle these non-standard builds by
always passing '-nolisten tcp' on the command line when tcp should
be disabled, and likewise always passing '-listen tcp' on the command
line, assuming the X server is new enough to support it, when tcp
should be enabled.

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 2/2] manager: Fix btmp record accounting
Before a user logs in they don't have a display.
btmp records currently need a display though, and they
get written when the user can't log in.
Furthermore, the display from X11 point of view is
somewhat archaic. We use wayland by default now.
In lieu of a display, this commit gives the btmp record
the seat id instead.

Subject: [PATCH 3/4] 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.

Subject: [PATCH 3/4] xdmcp-display-factory: Set supported session types for
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 4/4] daemon: handle upgrades from RHEL 7
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 4/4] local-display-factory: Don't crash if Xorg and Wayland
are both unavailable
At the moment if Wayland doesn't work, the login screen will fall back
to Xorg, and if Xorg doesn't work the login screen will fall back to
Wayland.
But if the fall back choice is disabled explicitly, GDM will just crash.
This commit fixes the crash.
Closes: https://gitlab.gnome.org/GNOME/gdm/-/issues/739
