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	 signifi
       cant server resources.

       Detailed	 information about a particular extension is dis
       played with the -ext extensionName option.  If  extension_
       Name 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.

       X(1), xwininfo(1), xprop(1), xrdb(1)
