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.

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 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 2/2] 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 3/4] common: Reload settings when graphics initialize
If GDM starts faster than graphics initialize, then the
udev rules that write out /run/gdm/custom.conf might get
run too late for GDM to notice.
This commit changes GDM to reread its config after graphicals
initialization completes.

From d76d6ff0761d47df938f1dab0daeeecac2feb56e Mon Sep 17 00:00:00 2001
From: Ray Strode <rstrode@redhat.com>
Date: Mon, 6 Sep 2021 08:43:28 -0400
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>
Date: Thu, 7 Oct 2021 15:34:27 -0400
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
