Fbdev backend was deprecated in the Weston 10.0.0 release with
6338dbd581. Before that, I suggested
already in 2019 to remove it, but it was too soon then. Now it seems the
final voices asking for fbdev to be kept have been satisfied, see the
linked issue.
Fbdev-backend uses a kernel graphics UAPI (fbdev) which is sub-par for a
Wayland compositor: you cannot do GPU accelerated graphics in any
reasonable way, no hotplug support, multi-output support is tedious, and
so on. Most importantly, Linux has deprecated fbdev a long time ago due
to the UAPI fitting modern systems and use cases very poorly, but cannot
get rid of it if any users remain. Let's do here what we can to reduce
fbdev usage.
I am doing color management related additions to libweston which require
adding checks to every backend. One backend less is less churn to write
and review.
Libweston major version has already been bumped to 11, so the next
release will be Weston 11, without fbdev. enum weston_compositor_backend
entries change their numerical values.

When using the libseat launcher, there is one more detail to take care:
stop libseat from managing the VT.
A normal user does not have permissions to manage a VT, so launching
would just fail. In this use case you also do not want to be managing
the VT, because your normal desktop is already owning the seat
associated with the VT.

Give a little more details about how running Weston via ssh or serial
terminal is best done, now that launcher-direct and weston-launch are
gone.
Hopefully the removal of launcher-direct also makes less people run
Weston as root, when seatd is the privileged process. Running 'weston'
as root might still work through libseat's builtin backend without
seatd.

Moving forward we're going to be supporting libseat and logind as our
only launchers. We're doing this to reduce our maintenance burden,
and security impact.
Libseat supports all our existing use cases, and seatd can replace
weston-launch so we no longer have to carry a setuid-root program.
This patch removes weston-launch, and launcher-direct, leaving only
libseat and logind.

With the recent changes, weston could be started as user service. This
adds some examples and howtos one might do that. Includes some simple
systemd unit files.

Documentation file for explaning in more detail how to run weston, using
launcher direct and specifying a non-default seat. This explains how to
create a udev file and assign a particular GPU card to it, and
potentially, other input devices. It also describes a bit additional
arguments that can be passed on, as an introduction to using the DRM
node for that particular seat.
