power saving functions for your monitor. Basically it lets your monitor
suspend and power off automatically from inactivity. It is nice So
lets see how we set it up!

      First, the requirements. You will need X Windows (XFree86 4.x or
X.org 6.7 or greater). You will also need an X Server that supports the
DPMS calls (to the best of my knowledge basically every X Server out
there supports this now).

      Next we need to make a few modifications to our X config file (XF86Config, XF86Config-4 or xorg.conf).

In the Monitor section add:

Windows for you. Enjoy your cooler room and lower power bill
