xdpyinfo - display information utility for X
SYNOPSIS
xdpyinfo [-display displayname]
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.
