Historique du projet

The X.Org manpage credits Keith Packard of the MIT X Consortium as author and says the program was copied from a NeWS version apparently written by Jeremy Huxtable as seen at SIGGRAPH 1988. In X.Org packaging it became an app module described by freedesktop.org as a 'follow the mouse' demo using the X SHAPE extension.

Like other X.Org applications, xeyes moved into the modular source-release world after X11R7.0 split the old monolithic tree into separately released modules. Its freedesktop.org GitLab project was created during the 2018 migration period and keeps the small app maintained with the rest of the X.Org app family.

Historique d'adoption

xeyes spread because it was small, visual, funny, and included with X tool collections. It gave users an immediate sign that X applications were working, while developers used it as a simple demonstration of shaped windows and pointer tracking.

In the Wayland era, xeyes gained a second life as a diagnostic joke with practical value: because it follows the pointer through X11 mechanisms, users can use its behavior to infer whether an application is running as an X11 client, through XWayland, or outside xeyes' visibility.

Modes d'utilisation

The ordinary usage is simply to run xeyes and watch the pupils track the cursor. Options adjust colors, geometry, backing store, SHAPE usage, Xrender antialiasing, and the alternate distance mapping.

Packagers and desktop troubleshooters use it as a minimal GUI test because it starts quickly, has no configuration, needs only the X display path, and makes failure obvious.

Pourquoi les passionnés de paquets s'y intéressent

xeyes is package-manager whimsy with a real technical payload. It demonstrates that not every useful package is serious; sometimes the tiny demo program is the fastest way to prove a display stack, extension, or compatibility layer is behaving as expected.

Its survival also shows how X.Org's modular app packages preserve small historical clients that would be lost if only large desktop environments were packaged.
