       xdpyinfo - display information utility for X


       xdpyinfo  [-display  displayname]  [-queryExtensions]  [-ext extension-
       name] [-version]


       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

       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

       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.
