NAME
xdpyinfo − display information utility for X.
SYNTAX
xdpyinfo [option]
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. See Chapter 8, Other Clients, for more information.
OPTION
xdpyinfo accepts the following option:
-display [host]:server[.screen]
Specifies the display about which xdpyinfo should display information. host is the hostname of the physical display, server specifies the server number, and screen specifies the screen number. By default, xdpyinfo displays information about all screens on the display. For example, % xdpyinfo -display your_node:0.0 displays information about all screens of server 0 of the display named by your_node. If the hostname is omitted, the local display is assumed. If the screen is omitted, screen 0 is assumed. The server and colon (:) are necessary in all cases.
SAMPLE OUTPUT
The following example shows the output produced by xdpyinfo when connected to a display that supports an 8-plane screen and a 1-plane screen. name of display: :0.0 version number: 11.0 vendor string: MIT X Consortium vendor release number: 4 maximum request size: 16384 longwords (65536 bytes) motion buffer size: 0 bitmap unit, bit order, padding: 32, MSBFirst, 32 image byte order: MSBFirst number of supported pixmap formats: 2 supported pixmap formats:
