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 avail‐
       able.

       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.
