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 capabil‐

ities 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 dis‐

played. 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.
