.SH DESCRIPTION
|
|
.PP
|
|
.I 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.
|
|
.PP
|
|
By default, numeric information (opcode, base event, base error) about
|
|
protocol extensions is not displayed. This information can be obtained
|
|
with the \fB\-queryExtensions\fP 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.
|
|
.PP
|
|
Detailed information about a particular extension is displayed with the
|
|
\fB\-ext\fP \fIextensionName\fP option. If \fIextensionName\fP is
|
|
\fBall\fP, information about all extensions supported by both \fIxdpyinfo\fP
|
|
and the server is displayed.
|
|
.SH ENVIRONMENT

|
.PP
|
|
.TP 8
|
|
.B DISPLAY
|

To get the default host, display number, and screen.
