Instead of having each search function print its various test decisions,
print the full state at the end of every search. This makes it much
clearer what state a particular test includes.
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.
When storing a config, we need to find the output that is being
configured to extract its identifier. output_by_name_or_id does not
return outputs that are disabled, and using this makes it impossible to
merge configurations related to disabled outputs.
Switch to all_outputs_by_name_or_id.
Fixes: https://github.com/swaywm/sway/issues/8141
If there is no output currently connected, we still want to merge
to any existing config.
It shouldn't matter to iterate over the list of outputs to do
nothing anwyays.

Fixes: 1267e47de9 ("config/output: Refactor handling of tiered configs")
Output configuration can be applied to a particular output in three
ways: As a wildcard, by connector name and by identifier. This in turn
means that three different configurations must be handled at any given
time.
In the current model, this is managed by merging new configuration into
every other matching configuration. At the same time, an additional
synthetic configuration is made which matchehes both identifier and name
at the same time, further complicating logic.
Instead, manage and store each configuration independently and merge
them in order when retrieving configuration for an output. When changes
are made to a less specific configuration, clear these fields from more
specific configurations to allow the change to take effect regardless of
precedence.
Fixes: https://github.com/swaywm/sway/issues/8048
apply_output_config_to_outputs uses the specified output config to check
which outputs to apply to, and to use as backup when no config is found.
If any config matches the output, the specified config will be
disregarded.
The only remaining user of apply_output_config_to_outputs is
reset_outputs, which called apply_output_config_to_outputs with either
the first stored wildcard config, or a new empty wildcard config.
Providing a stored or empty wildcard config is practically the same as
calling `apply_all_output_configs`. Replace uses of `reset_outputs` with
`apply_all_output_configs` and remove the now unused functions.
Introduce apply_output_configs, which applies the specified matched
output configs as a single backend commit.
Reimplement apply_output_config_to_outputs using apply_output_configs.
Applying an output config has two stages: Atomic application of
wlr_output_state, and applicaiton of non-atomic state like output
layout.
Split the latter out into finalize_output_config for use in a later
commit.
This doesn't catch the error if a background changing command is
executed via swaymsg, but improves logging.
The additional checks at least propagate if e.g. forking failed.
Previous behavior was that only if resolution and refresh rate match
exactly, the mode was accepted. As fallback, the mode with the highest
refresh rate and the same resolution was chosen.
New behavior is that the mode with the closest match for the refresh
rate is used with a limit of up to 1Hz. The fallback behavior stays the same.
Additionally, the logging was made more verbose.
This makes it possible to hint to the renderer and backends how many
bits per channel the buffers that the compositor draws windows onto
should have. Renderers and backends may deviate from this if they
do not support the formats with higher bit depth.
Wayland compositors handle many file descriptors: client
connections, DMA-BUFs, sync_files, wl_data_device pipes, and so
on. Bump the limit to the max.
Closes: https://github.com/swaywm/sway/issues/6285
Sometimes the preferred mode is not available due to hardware
constraints (e.g. GPU or cable bandwidth limitations). In these
cases it's better to fallback to lower modes than to end up with
a black screen.
Before this commit, when an output had its scale dynamically changed,
Sway would not load a cursor theme with the new scale. This results
in stale cursor images when moving the cursor into an area controlled
by the compositor, like the background or resize areas.
To reproduce:
- Using IPC, set an output scale to a value that isn't currently used
- Move the cursor into a compositor-controlled area
- The cursor will not change
Previously, we called output_disable prior to wlr_output_commit. This
mutates Sway's output state before the output commit actually succeeds.
This results in Sway's state getting out-of-sync with wlroots'.
An alternative fix [1] was to revert the changes made by output_disable
in case of failure. This is a little complicated. Instead, this patch
makes it so Sway's internal state is never changed before a successful
wlr_output commit.
We had two output flags: enabled and configured. However enabled was set
prior to the output becoming enabled, and was used to prevent the output
event handlers (specifically, the mode handler) from calling
apply_output_config again (infinite loop).
Rename enabled to enabling and use it exclusively for this purpose.
Rename configure to enabled, because that's what it really means.

We are not allowed to do what we did in #5222 and pass a `NULL` surface
wlr_seat_pointer_notify_enter(), and it's causing crashes when an
xdg-shell popup is active (see #5294 and swaywm/wlroots#2161).
Instead, solve #5220 using the new wlroots API introduced in
swaywm/wlroots#2217.
Previously in 3de1a39, it "worked by accident" in my testing since the
display being used in `map_to_output` was initialized first (the map
would not be applied because the display hadn't actually come online
yet), and was followed by a second display (at which point the map would
get applied for the first display).
Refs #5231
Some input rules, like `map_to_output`, are dependent on a specific
screen being present. This currently does not work for hotplugged
outputs, or outputs that are processed after the input device is
initially probed.
This commit fixes both cases, by reconfiguring inputs on each output
addition.
Fixes#5231.
An if branch takes care of the case where the output needs to be turned
off (DPMS'ed or disabled). The other branch needs to unconditionally
enable the output.
output->current_mode is already taken care of in apply_config.
Sorry about that, probably made a bad change by mistake after my DRM testing.
Closes: https://github.com/swaywm/sway/issues/5193
This enables/disables adaptive synchronization on the output.
For now, the default is disabled because it might cause flickering on
some hardware if clients don't submit frames at regular enough
intervals. In the future an "auto" option will only enable adaptive sync
if a fullscreen client opts-in via a Wayland protocol.
The output manager config is created when the output is created. It is
updated when the mode, transform, scale, or layout for the output
changes, as well as, when the output is destroyed.
Since the output->enabled property was not being set before calling
apply_output_config, the output event handlers were early returning and
never updating the output manager config when the output state was
committed.
This fixes the issue by setting output->enabled in apply_output_config
below the output disabling section. There are also a few other minor
changes that are required to function.
Additionally, this renames output_enable to output_configure to better
describe the recent changes.
