NAME
     xdpyinfo - displays information about an X server

SYNOPSIS
     xdpyinfo [-display display]

DESCRIPTION
     xdpyinfo displays information about an X server.  It is used
     to examine the capabilities of a server, the predefined
     values for various parameters used in communicating between
     client applications and the server, and the different types
     of screens and visuals that are available.

EXAMPLE
     The following example of xdpyinfo output was produced using
     a display that supports an 8-plane (8-bit-deep) screen and a
     1-plane (1-bit-deep) screen.
