Descrizione
Is your feature request related to a problem? Please describe.
Currently, ML4W provides ml4w-toggle-hyprsunset to switch the blue-light filter on and off manually via keybinding (SUPER + SHIFT + H).
While this works, users have to remember to press the shortcut every single evening. If the PC is booted after 20:00 or woken up from suspend, the screen remains at full cold brightness. A modern desktop night-light should ideally be fully automated based on the time of day (like Night Light on Android, iOS, Windows, or macOS) without requiring manual intervention every evening.
Describe the solution you'd like
A native, zero-overhead day/night scheduler using systemd user timers:
- Native systemd Timers (0% CPU Overhead):
- Daily timer at 20:00 to enable the filter.
- Daily timer at 07:00 to disable the filter.
Persistent=trueensures missed triggers (e.g. while suspended or powered off) execute immediately upon resume.
- Boot / Login Session Sync:
- A lightweight init script run on Hyprland startup checks the current hour. If the PC boots at 22:00, it immediately applies the warm filter without waiting for the next timer.
- Consistent Manual Toggle:
- The manual shortcut toggles the
hyprsunset.serviceviasystemctl --user, keeping the timer states and manual overrides completely in sync.
- The manual shortcut toggles the
- Dynamic Temperature:
- Automatically reads the desired Kelvin value from
~/.config/ml4w/settings/hyprsunset-temp(default: 4500K).
- Automatically reads the desired Kelvin value from
Describe alternatives you've considered
- Background loop in Bash (
while true; sleep 60): Wastes CPU cycles, adds unnecessary background processes, and can easily desync during system suspend. - GLSL Fragment Shaders (like PR #1819): Great for grayscale or color inversion, but for blue-light filtering,
hyprsunsetwith hardware gamma LUTs is superior (keeps screenshots un-tinted, supports arbitrary Kelvin values, 0% GPU overhead). - External daemons (
wlsunset,gammastep): Unnecessary sincehyprsunsetis already the official tool and part of ML4W.
Additional context
I have already tested this entire architecture thoroughly in daily use with zero issues.
I've attached the complete, ready-to-use package (including all 5 systemd unit files, helper scripts, automated install script, and documentation) as a ZIP file so you can easily review and test it whenever you have time.
