30 xdpyinfo \- display information utility for X
33 [\-display \fIdisplayname\fP]
35 [\-ext \fIextension-name\fP]
39 is a utility for displaying information about an X server. It is used to
41 capabilities of a server, the predefined values for various parameters used
42 in communicating between clients and the server, and the different types of
43 screens and visuals that are available.
45 By default, numeric information (opcode, base event, base error) about
46 protocol extensions is not displayed. This information can be obtained
47 with the \fB\-queryExtensions\fP option. Use of this option on servers
48 that dynamically load extensions will likely cause all possible extensions
49 to be loaded, which can be slow and can consume significant server resources.
51 Detailed information about a particular extension is displayed with the
52 \fB\-ext\fP \fIextensionName\fP option. If \fIextensionName\fP is
53 \fBall\fP, information about all extensions supported by both \fIxdpyinfo\fP
54 and the server is displayed.
59 To get the default host, display number, and screen.
