Introduction to XScreenSaver
The XScreenSaver package is a
modular screen saver and locker for the X Window System. It is
highly customizable and allows the use of any program that can draw
on the root window as a display mode. The purpose of XScreenSaver is to display pretty pictures on
your screen when it is not in use, in keeping with the philosophy
that unattended monitors should always be doing something
interesting, just like they do in the movies. However, XScreenSaver can also be used as a screen
locker, to prevent others from using your terminal while you are
away.

Linux PAM Configuration

to create a PAM configuration
file, to get it working correctly with BLFS.
Issue the following commands as the root user to create the configuration file
for Linux PAM:
cat > /etc/pam.d/xscreensaver << "EOF"
# Begin /etc/pam.d/xscreensaver
auth include system-auth
account include system-account
# End /etc/pam.d/xscreensaver
