YaLTeR/niri
Niri
Niri is a Wayland compositor that provides a desktop environment for Linux. Its primary purpose is to implement a scrollable tiling window management system, which organizes application windows in a non-overlapping layout that allows horizontal scrolling to access content beyond the screen edge.
The compositor features multi-monitor workspace coordination, managing window arrangements and fractional scaling across displays with different resolutions and pixel densities. It supports a dynamic workspace organization model where independent vertical workspace stacks are maintained per monitor.
Additional capabilities include tabbed window grouping for task organization, gesture-based input control for touchpads and mice, and visual interface styling using GPU shaders for effects such as background blur and gradient borders. The system also integrates accessibility tools for screen readers and supports live configuration reloading to update settings without restarting the session.
Features
- Display Compositors - Implements a Wayland display compositor that manages window placement, input routing, and hardware-accelerated rendering.
- Multi-Monitor Workspace Managers - Manages the distribution and arrangement of windows across multiple screens and virtual spaces.
- Per-Monitor Workspace Stacks - Creates independent vertical workspaces for each monitor and preserves their arrangement across connection changes.
- Virtual Workspace Managers - Maintains isolated logical containers for application windows mapped to physical displays.
- Desktop Environment Components - Provides the graphical interface, window management, and core services for a Wayland-based desktop environment.
- Tiling Window Managers - Organizes application windows into non-overlapping tiled layouts for efficient screen usage.
- Column-Based Tiling - Organizes application windows into a scrolling, column-based layout that expands horizontally.
- Density-Independent Scaling - Calculates UI coordinates and surface sizes across monitors with differing pixel densities to ensure visual consistency.
- DPI Scaling - Automatically adjusts interface dimensions and font sizes across multiple monitors with mixed DPI settings.
- Configuration Hot-Reloading - Provides mechanisms for updating application state and settings dynamically without requiring service restarts.
- Tabbed Window Groupers - Consolidates multiple application windows into tabbed interfaces to organize active tasks.
- Workspace Overview Management - Provides a high-level zoomed-out view of all active workspaces to simplify navigation.
- Visual Effect Shaders - Uses custom GLSL shader implementations for real-time graphical effects like background blur and gradient borders.
- Live Configuration Watchers - Includes real-time monitoring and reloading of configuration files to update settings without restarting.
- Desktop Environment Customizers - Provides tools for personalizing the visual and functional aspects of the desktop interface in real time.
- Gesture Interaction Hooks - Detects and responds to complex user input gestures from touchpads and mice to trigger system actions.
- Visual Style Customization - Implements mechanisms for applying themes, gaps, borders, and shaders to modify the overall desktop appearance.
- Window Managers - Scrollable-tiling Wayland compositor.
