fix(asusd): wire Aura/AniMe power-state tasks and cancel on hotplug - #463
Thread a tokio::sync::watch cancel flag through CtrlTask::create_sys_event_tasks so device hotplug can stop logind/udev listeners between events (without aborting mid-write).
Wire AuraZbus::start_tasks → create_tasks so brightness/modes restore after sleep (Fixes #444).
Wire AniMeZbus::start_tasks → create_tasks so lid/suspend/AC off_when_* handlers actually run (Fixes #288).
Align AniMe event handlers with reload(): resume/lid/AC respect display_enabled and active lid/power restrictions; AC brightness uses display_brightness when plugged in.
Small cleanup: next_or_cancel + biased cancel race, shared start_hotplug_tasks, Option cancel sender only for CtrlTask devices.
Test plan
cargo check --all-targets
cargo test -p asusd (watch_cancelled_*, next_or_cancel_*)
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Device event listeners now stop when their associated device is removed, preventing background tasks from continuing after disconnection.
Laptop brightness and configured lighting mode are restored on wake when possible. Restoration failures are logged without interrupting other handling.
Brightness is also restored during shutdown, with failures logged.
Reliability
System event listeners now stop cleanly when cancellation is requested, while continuing to respond to sleep, wake, lid, and power events during normal operation.
The daemon now passes cancellation receivers to system-event tasks. Device removal signals cancellation before removing the corresponding HID device’s D-Bus object. AniMe and Aura task startup now starts event handlers after D-Bus registration.
Changes: Cancellable system-event listeners
Layer / File(s)
Summary
Cancellation and listener handling asusd/src/lib.rs
System-event listeners now select between cancellation and their event sources. Cancellation stops the listeners; existing event handling and lid-state deduplication remain. The daemon’s start_tasks retains its cancellation sender. Tests cover cancellation after the flag is set and when it is initially set.

AniMe and Aura task startup asusd/src/aura_anime/trait_impls.rs, asusd/src/aura_laptop/trait_impls.rs, asusd/src/aura_laptop/mod.rs, asusd/src/ctrl_platform.rs
AniMe and Aura startup now accepts cancellation receivers and starts tasks after D-Bus registration. Aura wake handling restores brightness and mode, and sleep and shutdown handling logs errors instead of unwrapping them. CtrlPlatform forwards its cancellation receiver to system-event task creation.
Device cancellation lifecycle
Layer / File(s)
Summary
Cancellation channel wiring and HID removal asusd/src/aura_manager.rs
The manager stores a cancellation sender with registered devices and passes receivers to AniMe and Aura task startup. During HID removal, it signals cancellation before removing each device’s D-Bus object.
If a lid or power query fails during suspend or resume, the AniMe display may be left in the wrong state until the next lid or power event. This is a narrow edge case, so the change is mergeable with a small follow-up.

[#288] AniMeZbus::start_tasks starts the system-event handlers. The handlers apply the configured lid, suspend, and power restrictions, and restore the display when allowed. [#444] AuraZbus::start_tasks starts the wake handler, which restores keyboard brightness and mode. The reported physical checks are not coding requirements.

Fix the AC-change handler: it sets battery brightness when AC is plugged in.
Before this PR, this handler never ran. start_tasks now calls create_tasks, so the handler is live for the first time.
When off_when_unplugged is false, the else branch ignores power_plugged. It writes pkt_set_brightness(brightness_on_battery) on every AC transition. When the user plugs in, the display therefore drops to the battery brightness and stays there. Only the unplug direction is correct.
Select the brightness by power state. Use display_brightness when plugged in. Use brightness_on_battery when on battery. Destructure display_brightness in the config pattern at lines 419-424.

Respect lid and power restrictions on resume.
When the display is enabled in the config, resume sends an enable packet even if the laptop is on battery or its lid is closed. The display can stay on despite the configured restriction. Reapply both restrictions before enabling the display or starting the wake animation.

The code does not establish that the brightness packet can turn on a disabled display. Skipping the write could also leave the wrong brightness for a later enable operation.

substituting a default value; leave the separate calls in
set_off_when_lid_closed and reload unchanged.

instead of duplicating the display policy, keeping the policy in one place. Add
a small unit test for anime_display_allowed that verifies its restriction
