The xlogo command is a fundamental X Window System client designed to simply display the iconic X logo. It serves primarily as a lightweight visual test for verifying the operational status and connectivity of an X server. Often used in debugging X installations or demonstrations, it confirms that an X display is accessible and rendering correctly. As a basic X client, it supports standard X Toolkit options for controlling its appearance and position on the screen, such as background and foreground colors, window geometry, and title. Despite its simplicity, xlogo is a classic utility, consuming minimal resources while providing immediate visual feedback of a functional X environment.

xlogo is a purely graphical display application; it provides no interactive functionality beyond closing its window. Its sole purpose is to display the logo and confirm basic X server operation.

Because of its minimal resource usage and simple display function, xlogo is frequently used by system administrators and developers for a quick visual test to ensure that an X server is running correctly and that network connectivity to it is established. It's often the first graphical application run to confirm a working X environment.

xlogo has been a fundamental part of the standard X Window System distribution since its early days (X11R1, 1987). It was created as a simple, illustrative client to demonstrate basic X server functionality and has remained a classic utility for testing and visual confirmation of X environment integrity.
