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 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
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.

If -version is specified, xdpyinfo prints its version and exits,
without contacting the X server.

ENVIRONMENT


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