blacklayer

A lightweight, per-monitor screen saver for Hyprland that automatically dims inactive displays and instantly restores them on focus.

✅ Works On

wlroots-based Wayland compositors(Hyprland, Sway, River, Wayfire, Hikari, Labwc(wlroots based) )

⚠️ PARTIALLY / LIMITED

GNOME (Wayland), KDE Plasma (Wayland) !Not tested!

[blacklayer.conf]

• Stores Blacklayer configuration and resource settings
• Blacklayer’a ait ayarların ve kaynakların tutulduğu dosyadır

[call-blacklayer.sh]

• Toggles Blacklayer by starting or stopping blacklayer-worker
• Çağrıldığında blacklayer-worker’ı başlatır veya tüm işlemleri sonlandırır (toggle)

[blacklayer-worker.sh]

• Counts idle time and activates the screensaver while hiding other UI elements
• Zamanı sayarak ekran koruyucuyu açar ve Waybar gibi diğer arayüzleri gizler

[blacklayer]

• Displays a fullscreen color, image, or animated GIF on the screen
• Ekranda tercihe göre sadece renk, resim ya da GIF oynatır

[event-driven.sh]

• Listens for input events and stops Blacklayer when user activity is detected
• Blacklayer aktifken çalışır ve mouse/etkileşim algılandığında ekran koruyucuyu kapatır

[generate-waybar-configs.sh]

• Generates one Waybar config per monitor from a single base config
• Tek bir config dosyasından her monitör için ayrı Waybar config’i üretir

[start-waybars.sh]

• Starts all Waybar instances simultaneously
• Tüm Waybar’ları aynı anda çalıştırmak için kullanılır
