Description
Graphical applications can communicate with the X server through a client-side X11 protocol library.
This package is a foundational dependency for X11 toolkits, window utilities, desktop components, and applications that need display-server communication. It does not add a visible app by itself; other software uses it to draw windows and process events.
X11 clients can interact broadly with the display environment. Use trusted applications when sensitive windows or keyboard input are present.
