These are undocumented, outdated protocols that have a better wlr-protocols
equivalent.

drm: legacy: issue a NULL modeset on disable
|
|
The DRM subsystem needs a NULL modeset for connectors which disappear
from the system to disable the hardware pipes, otherwise the pixels get
rendered but are sent nowhere.
The atomic backend does the equivalent by removing the properties and
issuing a commit.
Fixes #1706

If mmap fails, it will return MAP_FAILED not NULL. Since the error
handling was incorrectly checking for NULL, MAP_FAILED was being passed
to xkb_keymap_new_from_string, on mmap failure, causing a segfault.
This just fixes the error checking.

If an output is destroyed while an idle_done event is scheduled, it
results in the following Address Sanitizer Output:

session/logind: check for XDG_SESSION_ID first
|
|
In order to support compositors running as systemd user units without display manager,
a mechanism for specifying session ID exactly must exist.
Checking for `XDG_SESSION_ID` mimics loginctl behaviour https://github.com/systemd/systemd/blob/e95be7def26c6c5feaf08a4135aa4f50c53263a8/src/login/loginctl.c#L856.

session/logind: specify seat exactly
|
|
"/org/freedesktop/login1/seat/self" path triggers seat-finding code path in logind,
which currently relies on getting the session based on caller's PID.
This behaviour is deprecated in logind as it doesn't work eg. with systemd user units,
which run outside of user session.
We check for "seat0" in logind_change_vt() already as introduced in 47985d2dc56a6af469ac9375e7548136765aff16,
so hard-coding it here is not a problem, otherwise sd_session_get_seat() could be used.

session/logind: keep active for pause_device gone
|
|
When using the rdp backend and connecting with xfreerdp ... --rfx, wlroots
crashes in backend/rdp/output.c while attempting to realloc(..., 0).
This commit guards against that and instead returns true, resulting in
no rfx message being sent. This prevents the crash and appears to work, but
it's not obvious if this is correct from a specification perspective.
|
|
|
|
This appears to be a quick fix for compositors freezing when a dock is
disconnected. Disconnection of the dock is causing `pause_device` for
the DRM devices associated with the dock. Since these devices major
number is `DRM_MAJOR`, the session was being set to inactive. This just
makes it so the session is not set to inactive when the device's state
is `gone`.
|
|
This is often the name of the GPU and can help debugging graphics issues.
|
|
We bind to it but never use it.
|
|
This allows the toplevel to have proper decorations on compositors that support
xdg-decoration-unstable-v1.
|
|
|
|
|
|
This makes it so we don't miss build failures because the CI misses a
dependency.

Xwayland expects an xdg_output.done event to always be sent with a
wl_output.done event.
|
|
This commit introduces wlr_output_schedule_done and refactors the mechanism
used to send wl_output events to clients.
wlr_output_schedule_done schedules a wl_output.done event. This allows clients
to see wlr_output property changes as atomic.
This function is also useful for add-on interfaces like xdg_output which need
to trigger a wl_output.done event to apply their new state.
|
|
We want to damage the whole output in this mode. However if we overwrite the
damaged region after it's useless.

We only need to damage the parts of the screen that changed since last frame,
we don't need to accumulate damage from previous buffers.
We still need to re-render the accumulated damage.
Fixes https://github.com/swaywm/wlroots/issues/1665
|
|
According to the spec:
> If <n_rects> is 0 then <rects> is ignored and the entire
> surface is implicitly damaged and the behaviour is equivalent
> to calling eglSwapBuffers.
When we want to swap with an empty damage region, set the damage to a single
empty rectangle.
|
|
|
|
This does not require any code changes, as we already copy the keymap
data separately for each client.

This new name makes more sense, since it is a request from the backend to get
a new frame. In the future a commit may not convey a new frame.
