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.

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 1/4] local-display-factory: Stall startup until main graphics
card is ready
At the moment, GDM waits until systemd says the system supports
graphics (via the CanGraphical logind property).
Unfortunately, this property isn't really what we need, since it flips
to true when *any* graphics are available, not when the main graphics
for the system are ready.
This is a problem on hybrid graphics systems, if one card is slower to
load than another. In particular, the vendor nvidia driver can be slow
to load because it has multiple kernel modules it loads in series.
Indeed on fast systems, that use the vendor nvidia driver, it's not
unusual for boot to get to a point where all of userspace up to and
including GDM is executed before the graphics are ready to go.
This commit tries to mitigate the situation by adding an additional,
check aside from CanGraphical to test if the system is ready.
This check waits for the graphics card associated with boot to be fully
up and running before proceeding to start a login screen.
Closes: https://gitlab.gnome.org/GNOME/gdm/-/issues/763

Subject: [PATCH] session-settings: Fetch session from user even if user isn't
cached
Now that accountsservice supports session templates, GDM can't assume
that no-cache file means, there's nothing worth reading.
Unfortunately, GDM does exactly that. It bypasses fetching the users
session if it doesn't think the user has one.
This commit removes that no-longer-correct optimization.

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 1/5] 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 2/4] common: Add API to reload settings from disk
Ideally we would reread /run/gdm/custom.conf after we've decided
graphics setup is complete. This is because the file may not
get written out by udev until after GDM is already started and waiting.
As a first step to get there, this commit adds an API for rereading
the file, and changes the SIGHUP handler to use it (instead of
the complete teardown and reinitialization it was doing before).

Subject: [PATCH 2/5] 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.

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.

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: 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.

From d76d6ff0761d47df938f1dab0daeeecac2feb56e Mon Sep 17 00:00:00 2001

Subject: [PATCH 4/5] daemon: Consolidate session-type and
supported-session-types list
There's currently a bug in computing the session-type to use.
The `i > 0` check means wayland will overwrite x11 in the
transient session type list.
Morever, the separation between "session-type" and
"supported-session-types" is a little redundant. Since
supported-session-types is a sorted list, the first item should
always be the same as "session-type".
This commit addresses the bug and the redundant logic, by computing
the supported session types early in the function and indexing into
it to get the session-type.
A future cleanup could probably get rid of session-type entirely.

Subject: [PATCH 4/4] data: Use latest upstream udev rules
This pulls in the latest udev rule from upstream that gives us
wayland on nvidia when we can, and disables wayland on nvidia
when we should.
It also pulls in the latest handling for passthrough gpus.

From 0e467e3fb32d9e2a7499069699527638eb2c2be1 Mon Sep 17 00:00:00 2001
From: Ray Strode <rstrode@redhat.com>

Subject: [PATCH 5/5] 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
