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.
Note
Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Installation of XScreenSaver
Change a hardcoded library name, which prevents using the settings found by configure:
sed -i 's/-lsystemd/-lelogind/' driver/Makefile.in
Install XScreenSaver by running the following commands:
./configure --prefix=/usr &&
make
This package does not come with a test suite.
Now, as the root
user:
make install
Configuring XScreenSaver
Config Files
/etc/X11/app-defaults/XScreenSaver
and ~/.xscreensaver
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
