On the drm output the wlr_drm_connector structs are reused.
This struct contains the wlr_output struct, which is reused as well.
The old code kept modes/edid and output state persistent over hotplug.
This nulls the relevant strings, reads newer edid data and removes old
modes on unplug.
The backend destroy signal is emitted before the output_remove
signal is. When the destroy signal is emitted listeners remove
their output_remove listener, so the output_remove signal is never
received and listeners have an invalid output pointer.
The correct way to solve this would be to remove the output_remove
signal completely and use the wlr_output.events.destroy signal
instead. This isn't yet possible because wl_signal_emit is unsafe
and listeners cannot be removed in listeners.
The wlr_drm_surface_init function is called (upon others) when the drm
mode is changed.
When the surface was used previously this replaced the gbm_surface, but
did not replace the gbm buffers (front/back).
With this, wlr_drm_surface_get_from never set up the new buffers with
the new glViewport because surf->front existed.
This frees the buffers to get new buffers on the new surface with the
new viewport.
Right now, we are adding systemd and elogind backends to the build
system as soon as their libraries are found on the build system.
Instead, we should only add them if the libraries have been found _and_
the user has actually requested them to be included.
since we're looking at pointer differences.
Otherwise the build fails on arm like

This backports some changes to #319 to fix the screenshooter data
format. This also adds wlr_backend_get_renderer which will be
useful to support multiple renderers.
This adds back `wlr_output::needs_swap`. This allows a backend to
request buffer swaps even if the output isn't damaged. This is
needed by the DRM backend to trigger pageflips when the cursor
moves.
Same as what atomic_crtc_set_cursor does

Add a remote display name argument to wlr_wl_backend_create.
If NULL is passed to the wayland backend at all times, creating a
wayland backend *after* the compositor was started up, would require
changing the WAYLAND_DISPLAY environment variable.
Without this patch I'm getting the following build error when building

compilation terminated.
* Moved os-compatibility.c to util
* Added header under util
* Removed static since it isn't needed (i think so)
* Adjusted meson.build to include lib_wlr
Improved some codestyle
* Added guard to os-compatibility.h
* Fixed typo in include statment
Adjusted Guard
* Changed guard to _WLR_UTIL_OS_COMPATIBILITY
Xwayland uses SIGUSR1 to signal readiness.
With direct(-freebsd) session and Xwayland, wlroots was confusing the
Xwayland readiness signal with a vt switch signal, freezing the desktop.
Same problem was found in Weston in 2014:
