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 avail-
able.
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 re-
sources.
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, with-
out contacting the X server.
ENVIRONMENT
DISPLAY To get the default host, display number, and screen.
