Request:

You want to activate energy saving modes for your monitor.

Procedure:

The energy saving mode must be activated in the XFree86 4.0 config file. For this you need to edit the file /etc/X11/XF86Config. Go to the section Monitor that looks something like:

Section "Monitor"
  HorizSync     31.5-90
  Identifier    "Monitor[0]"
  ModelName     "DDC-Probed"
  VendorName    "DDC-Probed"
  VertRefresh   50-100
  UseModes      "Modes[0]"
EndSection

Add the option "DPMS" like this:

Section "Monitor"
  HorizSync     31.5-90
  Identifier    "Monitor[0]"
  ModelName     "DDC-Probed"
  VendorName    "DDC-Probed"
  VertRefresh   50-100
  UseModes      "Modes[0]"
  Option        "DPMS"
EndSection

After restarting the X server you can activate the energy saving modes with

xset dpms 600 1200 2400   # Standby, Suspend and Offtime in seconds
