+.SH USING GDM(1)
+Using xscreensaver with
+.BR gdm (1)
+is easy, because gdm has a configuration tool. Just fire up
+.BR gdmconfig (1)
+and on the \fIBackground\fP page, type \fB"xscreensaver -nosplash"\fP into
+the \fIBackground Program\fP field. That will cause gdm to run xscreensaver
+while nobody is logged in, and kill it as soon as someone does log in.
+(The user will then be responsible for starting xscreensaver on their
+own, if they want.)
+
+Another way to accomplish the same thing is to edit the
+file \fI/etc/X11/gdm/gdm.conf\fP to include:
+.EX
+BackgroundProgram=xscreensaver -nosplash
+RunBackgroundProgramAlways=true
+.EE
+In this situation, the \fIxscreensaver\fP process will probably be running
+as user \fIgdm\fP instead of \fIroot\fP. You can configure the settings
+for this nobody-logged-in state (timeouts, DPMS, etc.) by editing
+the \fI~gdm/.xscreensaver\fP file.
+.SH USING KDE (K DESKTOP ENVIRONMENT)
+I understand that KDE has invented their own wrapper around xscreensaver,
+that is inferior to
+.BR xscreensaver-demo (1)
+in any number of ways. I've never actually seen it, but I'm told that
+this is the way you disable it:
+.RS 4
+.TP 3
+\fB1: Switch off KDE's screen saver.\fP
+Open the ``\fIControl Center\fP'' and
+select the ``\fILook and Feel / Screensaver\fP'' page.
+Turn off the ``\fIEnable Screensaver\fP'' checkbox.
+.TP 3
+\fB2: Find your Autostart directory.\fP
+Open the ``\fILook and Feel / Desktop / Paths\fP'' page,
+and see what your ``Autostart'' directory is set to: it will
+probably be \fI~/.kde3/Autostart/\fP or something similar.
+.TP 3
+\fB3: Make xscreensaver be an Autostart program.\fP
+Create a file in your autostart directory
+called \fIxscreensaver.desktop\fP that contains the following five lines:
+.EX
+[Desktop Entry]
+Exec=xscreensaver
+Name=XScreensaver
+Type=Application
+X-KDE-StartupNotify=false
+.EE
+.RE
+.PP
+Now use xscreensaver normally, controlling it via the usual
+.BR xscreensaver-demo (1)
+and
+.BR xscreensaver-command (1)
+mechanisms.
