Not that I need to actually save electricity or anything I'd just like to turn things off after I'm not using my computer for awhile. How would I set it to turn off the monitor and hard drives after say 20 minutes.
xfree86 < 4.x - use xset +dpms
xfree86 => 4.x put an entry in /etc/X11/XF86Config-4 that says Option "dpms"
here is an example.
Code:Section "Monitor" Identifier "Monitor0" VendorName "Monitor Vendor" ModelName "Monitor Model" HorizSync 30-69 VertRefresh 50-160 Gamma 1.5 Option "dpms"
