About:
Libdmx is the client-side library for the X Window System's DMX (Distributed Multihead X) extension. It provides a C API that enables X11 applications to interact with a DMX server, which aggregates multiple physical displays into a single, unified virtual X screen. This allows for managing large, multi-monitor setups and creating virtual displays for testing or remote access.

Key Features:

Provides the client API for the X11 DMX extension
Enables querying and controlling DMX server display topologies
Facilitates seamless integration with existing X11 applications
Supports dynamic reconfiguration of multi-head display environments

Use Cases:

Building applications that manage or monitor large, multi-monitor X11 display farms
Developing software for virtual display creation and management
Integrating with DMX servers for advanced display configuration in enterprise environments

Alternatives:

X11 forwarding – X11 forwarding is for remote single-app display, whereas DMX with Libdmx creates a unified, high-performance desktop across multiple physical machines and displays.
VNC/RDP – VNC/RDP are remote desktop protocols for screen sharing; DMX is a multi-head X server architecture that aggregates displays into a single X session.
