About:
Xeyes is a classic X Window System utility that displays a pair of cartoon eyes which track the cursor's movement across the screen. It demonstrates the X SHAPE extension by using a non-rectangular window mask to render the eyes and pupils. While primarily a fun demonstration of X11 capabilities, it also serves as a useful tool for verifying input device functionality and window manager behavior.
Key Features:
  • Real-time cursor tracking with animated eye movement
  • Utilizes the X SHAPE extension for non-rectangular window masking
  • Low resource usage and minimal system footprint
  • Configurable appearance through X resources
Use Cases:
  • Demonstrating X11 graphical capabilities and extensions
  • Verifying mouse input and window manager functionality
  • Providing visual feedback for remote X11 sessions
Alternatives:
  • xclock – Standard X11 clock utility; less graphical but more functional for timekeeping
  • xlogo – Displays the X Window System logo; similar demo purpose but static
