13 Xdpyinfo is a utility for displaying information about an X server. It
14 is used to examine the capabilities of a server, the predefined values
15 for various parameters used in communicating between clients and the
16 server, and the different types of screens and visuals that are avail‐
17 able.
18
19 By default, numeric information (opcode, base event, base error) about
20 protocol extensions is not displayed. This information can be obtained
21 with the -queryExtensions option. Use of this option on servers that
22 dynamically load extensions will likely cause all possible extensions
23 to be loaded, which can be slow and can consume significant server
24 resources.
25
26 Detailed information about a particular extension is displayed with the
27 -ext extensionName option. If extensionName is all, information about
28 all extensions supported by both xdpyinfo and the server is displayed.
29
30 If -version is specified, xdpyinfo prints its version and exits, with‐
31 out contacting the X server.
32
34 DISPLAY To get the default host, display number, and screen.
