Instead of using a single finalized output config per output, accept a
regular list of output configs like the one ultimately stored for
configuration purposes. This allows the output management code to test
an augmented configuration while still using the same output config
logic, without having to mutate the stored configuration.
This in turn allows us to make a few APIs private. A bug note about an
existing issue with derade to off is added as well.
If the output is not active, it might not have a valid geometry to
arrange for. Outputs do not gain a geometry until modeset, so if an
output is connected with a configuration present to disable it, it will
not have a geometry. If the output has a past workspace restored, this
will be attemtped arranged to fit a 0x0 rectangle, which asserts when
trying to sort out borders.
Consider the workspace activated only if the output itself is active to
get the scene nodes disabled.
Output layout changes originate from the centralized modeset
infrastructure and request_state which already takes care of arranging
and updating outputs as needed.
The reasoning for using a commit handler is to ensure that all paths for
output changes are correctly handled. With the centralized modeset
infrastructure in place, we can move the logic there. This allows us to
be smarter and avoid extraneous arranges, output manager updates and
transaction commits.
The side-effect is a minor duplication for the special-case
request_state, but the shared path will be relied upon further in future
commits to justify this duplication.
daaec72ac0 ("desktop/xwayland: restack surface upon activation")
has updated Sway for wlroots commit bfc69decdd04 ("xwm: do not
restack surfaces on activation"). However, it unconditionally
restacks the window above all other windows even if marking the
window as inactive.
Closes: https://github.com/swaywm/sway/issues/7974
Commit 188811f808 ("scene_graph: Port layer_shell") accidentally
removed code in `arrange_layers` to handle focus on layer shell
surfaces with keyboard interactivity.
Due to this, layer shell surfaces requesting exclusive keyboard
interactivity may not get automatically focused, and layer shell
surfaces giving up exclusive keyboard interactivity can remain focused.
Add the previous code back to fix the problem.
Note the non-rename change included in b4d7e84d38 ("desktop: Rename
layers to shell_layers") is not included as it also seems accidental.
Fixes: #7936
1e0031781f refactored repaint to accumulate all changes in a single
wlr_output_state and commit them at the end of the repaint loop,
replacing a call to wlr_scene_output_commit. wlr_scene_output_commit
contains an early bail-out when no frame has been requested and no
damage has accumulated, which was not replicated as part of this
refactor, causing the repaint loop to never pause.
Replicate the logic to stop the repaint loop as needed.
Fixes: 1e0031781f ("desktop/output: unify page-flip codepath")
the surface isn't initialized yet when we first handle it in
`handle_xdg_shell_toplevel`, move setting WM capabilities to
handle_commit instead.
Fixes warnings from wlroots about a configure being scheduled for
uninitialized surface
Instead of having a special codepath for applying gamma LUTs, have
a single codepath for regular page-flips and gamma LUT updates.
Should make it easier to add more logic on top e.g. for tearing
page-flips.
We were only passing the color transform when calling
wlr_scene_output_commit(). However when modesetting or pushing a
new gamma LUT we render via wlr_scene_output_build_state(). Pass
the color transform there as well.
The only reason it's included there is for a declaration of
struct sway_server, but we can just forward-declare it.
This avoids rebuilding almost all of Sway when touching server.h.
All other server.h includes are from source files, not headers.
Instead of having a build-time option to enable/disable xwayland
support, just use the wlroots build config: enable xwayland in
Sway if it was enabled when building wlroots. I don't see any
use-case for disabling xwayland in Sway when enabled in wlroots:
Sway doesn't pull in any additional dependency (just pulls in
dependencies that wlroots already needs). We have a config command
to disable xwayland at runtime anyways.
This makes it so xwayland behaves the same way as other features
such as libinput backend and session support. This also reduces
the build matrix (less combinations of build options).
I think we originally introduced the xwayland option when we didn't
have a good way to figure out the wlroots build config from the
Sway build system.
The original sway output config implementation enabled one output at a
time, testing modes, render formats and VRR support as it went along.
While this sort of fallback is easy to do, it has the downside of not
considering the effect of neighbor outputs on the configuration
viability.
With backend-wide commits, we can now better consider the effect of
neighbor outputs, but to handle the fact that we commit all outputs at
once we need to perform a more elaborate search of viable
configurations.
Implement a recursive configuration search for when the primary
configuration failed to apply.
We want to check if a config_head existed for the current
matched_output_config, so we should check cfg->output. sway_output is a
temporary variable from a previous wl_list_for_each, and does not
contain anything useful to us.
Fixes: https://github.com/swaywm/sway/issues/8128
Check if the app that requested a token has provided a valid input
serial and a focused surface. Downgrade activation request to urgency
otherwise.
This is mostly in line with what other Wayland compositors decided to
do, and offers a better security than the original logic.
We tried to synchronize layer shell popups with the parent layer shell
on commits, but this is subtly wrong because we would only update
the position for one layer shell that was committed, but not any other
layer that might be affected. By moving handling to the scene descriptor
we can iterate all popups and ensure they are synchronized.
