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 possi-
       ble extensions to be loaded, which can be slow and can consume signif-
       icant 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 dis-
       played.

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