When we change the required dependencies for the DRM backend,
Meson might auto-disable the backend for users missing the new
requirements. This results in confused users [1] because they don't
notice the "drm-backend: NO" line burried in the Meson logs, and
then get a black screen when starting the compositor.
Update wlr_backend_autocreate() to refuse to create a backend with
only libinput (without DRM).
Users really wanting to start their compositor with a libinput
backend and without a DRM backend can manually set WLR_BACKENDS.

Replace our current logic to setup the primary swapchain with
wlr_output_configure_primary_swapchain().
- Removes some code, reducing duplication
- Stop overwriting wlr_output.swapchain with a yet-to-be-tested
swapchain: remove the error_destroy_swapchain label.
We've had this struct for a while. It'd be useful for compositors
if they want to manage the swap chains themselves instead of being
forced to use wlr_output's. Some compositors might also want to use
a swapchain without an output.
X11 clients expect a ConfigureNotify after a ConfigureRequest. If
the compositor/window manager chooses not to honor the request
(e.g. due to the window being maximized), XWayland will not send a
"real" ConfigureNotify event and the window manager is expected to
send a synthetic event instead. Otherwise, the X11 client is left
waiting and may not repaint its window properly.
For comparison, see Openbox's client_configure() or Weston's
weston_wm_window_send_configure_notify().
v2: Move logic to wlr_xwayland_surface_configure()
This is based on previous work [1] [2].
This new API allows compositors to display buffers without needing to
perform rendering operations. This API can be implemented on Wayland
using subsurfaces and on DRM using KMS planes.
Compared to [1], this approach leverages wlr_addon_set to let backends
attach their own private state to layers, removes the pending
state (necessary for interop with wlr_output_commit_state()) and
enum wlr_output_layer_state_field.

Reverts commit c73e20628a.
This caused a regression in the GLES2 renderer because `egl->exts.EXT_device_drm` is set in
`egl_init_display()`, which is invoked after `get_egl_device_from_drm_fd()`. So the function will
always return `EGL_NO_DEVICE_EXT`.
This is needed for compositors that want to reserve space for
XWayland panels. Such a feature can be useful in a "transitional"
setup, where only the X11 window manager and compositor is replaced
but other components of an X11 desktop environment are still used.
This change simply reads the X11 property; the compositor is free
to ignore it. Thus, compositors that don't want to support such a
"transitional" feature are not impacted.
v2: Update xwayland_surface_associate()
The #sway-devel channel is now for Sway development only. #wlroots
is the new channel to use for wlroots.
We were using #sway-devel mostly for histerical raisins. Nowadays
many wlroots developers are not working on Sway.
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3586
options->scanout_primary_output indicates an output on which scanout is desirable.
Set the missing SCANOUT flag.
Fixes: 0c966f102c ("linux-dmabuf-v1: add wlr_linux_dmabuf_feedback_v1_init_with_options()")
This patch allows surfaces without keyboard focus
but with pointer focus to receive valid tokens.
This can be relevant for applications using an older version of
the layershell protocol which only provided the choice between
no keyboard focus and exclusive keyboard focus.
