About:
LibXrandr is the client-side library for the X Resize, Rotate, and Reflection (RandR) extension. It enables applications to dynamically manage display configurations, including screen resolution, refresh rates, and multi-monitor layouts. This library is essential for building display management tools and window managers on X11 systems.

Key Features:

Dynamic screen resolution and refresh rate adjustment
Support for multi-monitor configurations and screen rotations
Client API for the X Resize and Rotate Extension (RandR)
Introspection support for querying display capabilities

Use Cases:

Implementing dynamic resolution switching in window managers
Scripting monitor setup changes for desktop environments

Alternatives:

Wayland protocols – Modern replacement for X11; handles display management natively without separate extensions.
xorg-server – Provides the core display server; LibXrandr is the client library to interact with its RandR features.
