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.
