XWinGuard

XWinGuard is a software utility designed to enhance the security and management of X Window System displays, primarily in Unix-like environments. It functions as a screen locker and a display manager helper, offering features to protect unattended workstations from unauthorized access. The primary purpose of XWinGuard is to automatically lock the graphical session after a period of inactivity, requiring users to re-authenticate before resuming their work.

Key functionalities of XWinGuard include configurable timeout periods for automatic locking, customizable lock screens with optional messages, and the ability to restart the X session after a certain number of failed login attempts. It can be integrated with various display managers and desktop environments, providing a seamless user experience. The software is often used in multi-user environments or public access terminals where screen security is paramount. Its configuration options allow administrators to tailor the locking behavior to specific security policies. XWinGuard aims to provide a lightweight yet effective solution for securing X displays without imposing significant performance overhead.
