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	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  re-
       sources.

       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,	 with-
       out contacting the X server.

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