Recently I have been surprised to find out how many people don't seem to have DPMS setup on their Linux Desktops and it seems to be partially just cause they don't know how. So lets fix that.
First of all, what is DPMS? DPMS is the interface to the Energy Star 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).
Linux may be free, but up until now it definitely costs me a fair share on my electric bill. What I really want to see are some serious hardening of the suspend/standby/hibernate mode for the whole computer. If I leave for work and don't come home for 8 hours, I would expect that my computer is found sleeping when I get home. It offers the convenience of "leave me where I left off" and "wake on LAN" without having to do a full power cycle. What is the current status of the software suspend in Linux?
