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.
