XDPYINFO(1)        X Version 11 (Release 6.6)         XDPYINFO(1)


     NAME
          xdpyinfo - display information utility for X

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

     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.

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