http://crunchbang.org – Adjust your setting in your power manager for the screen not to fade for lets say 30mins. Then all you really need to do is move the mouse once every 30mins. I know it may not be the best solution but it works for me. When i walk away from my laptop i usually just close the lid and let it go to sleep so i have no need for the dim/screen off feature (HowTos)
