Software-managed LED persistence and power management for devices that
expose RGBEffects (0x8071) — primarily G515 LIGHTSPEED TKL, but the same
infrastructure works on any 0x8071 device that supports SW takeover.
Core mechanism: RGBControl toggle drives a Set SWControl(mode=3, flags)
handshake. While SW control is held, the host owns the LED pipeline: zone
effects, per-key paint, idle/sleep transitions, and the NvConfig boot/exit
animations. On release, the firmware resumes its onboard profile.
Major pieces:
- rgb_power.py — new module hosting the software RGB power manager:
ACTIVE / DIMMING / IDLE / SLEEPING state machine driven by firmware
onUserActivity events, smooth 5-second dim ramp (zone or per-key), idle
Static color snap, software sleep timer, wake handler that re-pushes
saved state. Includes the cleanup hook that runs on device close (and,
optionally, fires the cap 0x0040 shutdown trigger).
- RGBControl (settings_templates) — switch-style render via BooleanValidator
(true_value=3 / false_value=0) plus a full _claim_sw_control /
_release_sw_control pair: profile-management mode, SetSWControl, per-key
flag reset, manager start, cleanup registration, and a post-claim
repaint pass so the device immediately reflects Solaar's saved zone +
per-key state.
- RGBEffectSetting — zone-effect Setting subclass for 0x8071. Handles
per-key/zone coexistence: per-key paint dominates only when zone is
Static and the user has explicitly opted in via the lock icon; under
animations or before opt-in, the zone wire push is the visible layer.
- RGBIdleEffect / RGBIdleTimeout / RGBSleepTimeout — Solaar-managed idle
behavior. Choice list: "No change" → Dim → Static (snap to color) →
device-specific animations. Static idle substitutes the idle color for
unset per-key cells via effective_zone_base_color's state-aware lookup.
- RgbStartupAnimation / RgbShutdownAnimation — toggle-and-color rows for
RGBEffects NvConfig caps 0x0001 and 0x0040, exposed only on devices
that answer the probe. Shutdown trigger fires SetRgbPowerMode(0) at
cleanup time so the firmware plays the configured animation on exit.
- PerKeyLighting — per-key painter improvements: explicit-opt-in
dominance over zone effects, BUSY retry, FrameEnd suppression on
per-cell failure, single-shot prep sequence (SetEffectByIndex into the
out-of-range slot) on mice with firmware effect cards.
- device_quirks.py — small per-model quirks table keyed by device.modelId
(stable across USB/BLE/wireless). Currently used to mark RGBEffects
NvConfig color slots as inert on devices where the firmware accepts
but ignores the bytes (G502 X PLUS startup colors).
- config_panel.py — HeteroKeyControl gains a TOGGLE field kind that
renders as a Gtk.Switch (used by the boot-effect rows). Visual gate
greys out RGB settings whose prerequisites aren't met: rgb_zone_* /
rgb_idle_* / rgb_sleep_timeout require LED Control = Solaar; per-key
additionally requires every zone effect to be Static. Visual-only —
doesn't touch the persister's user lock-icon state.
- tests/test_rgb_power.py — coverage for the power manager state
machine, dim ramp, idle effects, wake path, and per-key/zone
coexistence.
