About:
libXdmcp is a client-side library that implements the X Display Manager Control Protocol (XDMCP). This protocol enables a display manager to authenticate and select an X server over a network. It is a foundational component for setting up remote X session management and display allocation.

Key Features:

Implements the XDMCP specification for networked X sessions
Provides APIs for client-side connection and authentication
Essential dependency for X Window System display managers
Lightweight and optimized for system integration

Use Cases:

Enabling remote X11 session logins via display managers like GDM or LightDM
Building custom X server clients that require network authentication
System-level configuration for headless servers with graphical login capabilities

Alternatives:

X11 forwarding (SSH) – Provides secure, encrypted X11 sessions over SSH, whereas XDMCP is typically unencrypted and used for network display management.
