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 capa‐
       bilities 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.
