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
This fixes the issue of the display freezing on reload with
wlroots#1545.
On master, all output configs are applied on reload. This may cause an
output to have its config applied up to three times, instead of just
once. The three cases are: output name, output identifier, and wildcard.
Not only is this inefficient, but it can cause swaybg to be spawned and
immediately killed.
However, swaybg requires two roundtrips of wl_display (to obtain needed
globals) before it enters its normal event loop. Modesetting will
roundtrip the wl_display. Without modesetting, waitpid for killing
swaybg could block infinitely due to swaybg being blocked by
wl_display_roundtrip.
This only configured an output once. It either uses the wildcard config
or creates an empty wildcard config and applies that. This also fixes a
bug where an output would not be reset when there is no output config to
apply to it.
On the DRM backend, if an output is dpms'd off and a different output is
hotplugged, the CRTC for the output is reclaimed. When modesetting an
output without a CRTC, a CRTC will not be given to an output that is not
desired to be enabled. This splits setting the dpms state in
apply_output_config. If the output should be dpms on, the it is enabled
before attempting to modeset. Otherwise, it is dpms'd off after setting
everything else.
This also adds DPMS_ON to the default output configs.
This commit mostly duplicates the wlr_log functions, although
with a sway_* prefix. (This is very similar to PR #2009.)
However, the logging function no longer needs to be replaceable,
so sway_log_init's second argument is used to set the exit
callback for sway_abort.
wlr_log_init is still invoked in sway/main.c
This commit makes it easier to remove the wlroots dependency for
the helper programs swaymsg, swaybg, swaybar, and swaynag.
This happens if you plug in more outputs than supported by your GPU.
This patch makes it so outputs without CRTCs appear as disabled. As soon as
they get a CRTC (signalled via the mode event), we can enable them.
Moves the call to `terminate_swaybg` from inside `apply_output_config` to
`output_disable`. The former was only called when an output was being
disabled. The latter is called when an output is being disabled and when
an output becomes disconnected. Without this, disconnecting an enabled
output would result in a defunct swaybg process.
Default output configs were generated on reload to reset an output to
its default settings. The idea was that anything that was removed from
the config or changed at runtime and not in the config should be reset
on reload. Originally, they were created using the output name. Recently,
they were changed to use the output identifier. It turns out that there
are issues of shadowing with that solution as well. This should fix
those issues.
Instead of generating the default output configs on reload and storing
them in the output config list to merge on top of, they are now only
generated when retrieving the output config for an output during a
reload. This means that the default output configs are never stored
anywhere and just used as a base to merge unaltered user configs on top
of during a reload.
Starting with a blank output config, merges get applied in the following
order:
1. Default output config (only during a reload)
2. Wildcard config (only if neither output name or output identifier
exist)
3. Output name config
4. Output identifier config
When generating default output configs to reset the outputs to their
default settings on reload, the output name was being used.
Additionally when determining the output config to apply, if there was
an output config with the output name, that was being used without
checking for an identifier config. This caused sway to completely ignore
the users specified output config.
To fix this issue, the following changes have been made:
1. Default output configs as created for the identifier now instead of
name. This actually makes more sense anyway since you could hotplug
multiple different outputs to the same port.
2. In get_output_config, which is only used to determine which output
config to apply, output configs for both the name and identifier are
queried. If both are found, a new output config is generated with the
identifier config merged on top of the name config. If just one is found,
a copy of that config is returned. This change also requires that the
result from get_output_config be freed after use to prevent memory
leaks, which required some minor changes to logic in
apply_output_config_to_outputs.
This changes it back so the path given to swaybg is enclosed in quotes.
Additionally, the only character that is escaped in the path stored is
double quotes now. This makes it so we don't need to keep an exhaustive
list of characters that need to be escaped.
The end user will still need to escape these characters in their config
or when passed to swaybg.
