+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 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.
+

+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.

+uninitialization.

+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 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.

+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.

+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.

+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.
