# 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

# If you want to disappear waybar when blacklayer is active follow these steps: 
sudo chown -R "$USER:$USER" ~/.config/waybar  
chmod 700 ~/.config/waybar  
cd ~/.config/blacklayer/  
```
./generate-waybar-configs.sh

Change these codes in your hyprland.conf document  
❌ exec-once = waybar &  
✅ exec-once = ~/.config/blacklayer/start-waybars.sh
