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
If XScreenSaver has been built with
Linux PAM support, you need 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
EOF
