XDPYINFO(1) X Version 11 (Release 6.6) XDPYINFO(1)
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 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.
ENVIRONMENT
DISPLAY To get the default host, display number, and screen.
