NAME
       xdpyinfo - display information utility for X

SYNOPSIS
       xdpyinfo [-display displayname] [-queryExtensions] [-ext extension-name]
       [-version]

DESCRIPTION
       Xdpyinfo is a utility for displaying 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 clients and the
       server, and the different types of screens and visuals that are
       available.

       By default, numeric information (opcode, base event, base error) about
       protocol extensions is not displayed.  This information can be obtained
       with the -queryExtensions option.  Use of this option on servers that
       dynamically load extensions will likely cause all possible extensions to
       be loaded, which can be slow and can consume significant server
       resources.

       Detailed information about a particular extension is displayed with the
       -ext extensionName option.  If extensionName is all, information about
       all extensions supported by both xdpyinfo and the server is displayed.

       If -version is specified, xdpyinfo prints its version and exits, without
       contacting the X server.

ENVIRONMENT
       DISPLAY To get the default host, display number, and screen.
