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.

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.
The only output_enable caller is now apply_output_config. Stop calling
apply_output_config from output_enable to simplify the code and avoid
the back-and-forth between these two functions.
output_enable is now the symmetric of output_disable: it just marks the
output as enabled and performs bookkeeping (e.g. creating teh default
workspace). It is called from apply_output_config after the output
commit, so that it can read the current output state and act
accordingly.
This change also allows us to avoid an extraneous wlr_output_commit.

If applying an output config to an output fails, the output may be
destroyed. To be able to handle this situation correctly,
apply_output_config_to_outputs needs to use wl_list_for_each_safe.
set_cloexec is defined by both sway and wlroots (and who-knows-else),
so rename the sway one for supporting static linkage. We also remove
the duplicate version of this in client/.
Fixes: https://github.com/swaywm/sway/issues/4677
Calling wlr_output_manager_v1_set_configuration with an enabled output
and a NULL mode is incorrect if the output doesn't support modes.
When DPMS'ing an output, wlr_output_enable(output, false) is called.
This de-allocates the CRTC and sets wlr_output.current_mode to NULL.
Because we mark DPMS'ed outputs as enabled, we also need to provide a
correct output mode. Add a field to sway_output to hold the current
mode.
Closes: https://github.com/swaywm/wlroots/issues/1867
When applying config, value mode->refresh is mHz; convert it to Hz before
assigning it to the temporary output config. oc->refresh_rate will
be converted back to mHz in set_mode function.
Fix debug log printing GHz instead of Hz.
When applying an output config, an output may transform or be altered
in some way that effects the cursor. In order for the cursor images to
be updated properly, all cursors need to be rebased after applying
output configs.
In apply_output_config, this sets output->{width,height} using the
values in the output box. Previously, they were being set using
wlr_output_transformed_resolution, which takes the width and height
from the wlr_output and just checks whether they should be swapped
based on the transform. This did not take into account the output's
scale. wlr_output_effective_resolution could be used instead, which
handles both transform and scale. However, the values in the output box
have already been processed by wlr_output_effective_resolution so they
can just be used directly
This fixes a typo in `merge_id_on_name` for output configs that
resulted in incorrect id-on-name output configs being generated.
Instead of using the output that matched the name or identifier, the
first output in the list was being used instead. This could cause
merging across unrelated output configs and preventing output configs
from being applied correctly
When reloading, this destroys the old config's swaybg client before
spawning the new config's swaybg. This fixes a race condition where the
old config's swaybg client's destroy was being called after the new
config's swaybg client was being spawned. This was causing the
reference to the new swaybg client to be removed and never destroyed.
This also modifies handle_swaybg_client_destroy to grab the config
reference using wl_container_of on the listener since the swaybg client
may be the old config swaybg client and should be used instead of the
global config instance
This makes it so there will only be one swaybg instance running
instead of one per output. swaybg's cli has been changed to a xrandr
like interface, where you select an output and then change properties
for that output and then select another output and repeat. This also
makes it so swaybg is only killed and respawned when a background
changes or when reloading.
Many laptop screens report unknown subpixel order. Allow users to manually set subpixel hinting to work around this.

In #3916, I overlooked that `get_output_config` does not handle
wildcards unless the config is reloading, which is a remnant of older
iterations of the output config handling that went unnoticed due to
`output_find_config` handling it. With the current version of the
output config handling, having `get_output_config` handle wildcard
configs is actually preferable. This fixes having only a wildcard
output config in the config file or when connecting/enabling a new
output with only a wildcard config existing.
This revamps the way that output configs are handled when referencing
an output by both identifier and name. If an output is always referred
to by name or by identifier, this should have no noticeable change. As
soon as there is a name output config and an identifier output config
that matches an output, an output config is generated that is named
`<identifier> on <name>` that is generated with the identifier output
config merged on top of the name output config and stored. When a
change to either is stored, the delta is merged on top of that
"id on name" output config, as well. If the "id on name" output config
exists, it has the highest precedence and will be used when applying
a config to the output.
This fixes the following case:
- `swaymsg output <name> bg /path/to/wallpaper1 fill`
- `swaymsg output <identifier> bg /path/to/wallpaper2 fill`
- `swaymsg output <name> dpms on`
Without this, the wallpaper is changed to `/path/to/wallpaper1`. With
this, the wallpaper remains `/path/to/wallpaper2`.
This removes `output_find_config`, which would take the first matching
output config it found. This is fine if only a name output config,
identifier output config, or even just wildcard exist, but if there is
a name output config and identifier output config, they are not merged.
Instead, this introduces find_output_config, which is just a wrapper
for `get_output_config`. This ensures that both the name and identifier
output configs are respected.
This fixes the following case:
- For simplicity in this example, remove all output configs from config
- Run `swaymsg output <name> bg #ff0000 solid_color`
- Run `swaymsg output <identifier> scale 2`
- Disconnect and reconnect output
Without this, the output will have the background, but not the scale.
With this, the output will have both the background and scale
