.SH NAME
xscreensaver - graphics hack and screen locker, launched when the user is idle
.SH SYNOPSIS
.BR xscreensaver-command (1)
programs.
.SH CONFIGURATION
-Options to \fIxscreensaver\fP are specified in one of two places: in
+The easiest way to configure \fIxscreensaver\fP is to simply run the
+.BR xscreensaver-demo (1)
+program, and change the settings through the GUI. The rest of this
+manual page describes lower level ways of changing settings.

+Options to \fIxscreensaver\fP are stored in one of two places: in
a \fI.xscreensaver\fP file in your home directory; or in the X resource
database. If the \fI.xscreensaver\fP file exists, it overrides any settings
in the resource database.

so that if you start \fIxscreensaver\fP with a \fI-display\fP argument, the
programs which \fIxscreensaver\fP launches will draw on the same display;

Modern X servers contain support to power down the monitor after an idle
period. If the monitor has powered down, then \fIxscreensaver\fP will

+.SH USING GDM(1)
+The instructions for using \fIxscreensaver\fP with
+.BR gdm (1)
+are almost the same as for using
+.BR xdm (1),
+above. There are only two differences, really: instead
+of editing \fI/usr/lib/X11/xdm/Xsetup\fP, edit the
+file \fI/etc/X11/gdm/Init/Default\fP; and instead of
+editing \fI/usr/lib/X11/xdm/Xsession\fP, edit one or all of the
+files in the \fI/etc/X11/gdm/Sessions/\fP directory. (Note that
+the default session (\fI/etc/X11/gdm/Sessions/Default\fP) usually
+simply executes \fI/usr/lib/X11/xdm/Xsession\fP, so be careful
+you aren't initializing xscreensaver twice.)
+
+All the same caveats apply for
+.BR gdm (1)
+as for
+.BR xdm (1).
.SH USING CDE (COMMON DESKTOP ENVIRONMENT)
The easiest way to use \fIxscreensaver\fP on a system with CDE is to simply
switch off the built-in CDE screensaver, and use \fIxscreensaver\fP instead;
