Thread: Resolution changes when I'm gone for a while

i set ubuntu 12.04 on parent's kinda new computer. works well, except 1 thing: resolution changes 1280x1024 1024x768 when coming inactivity. when go settings->displays automagically goes 1280x1024 without me needing press button. connected display crt default resolution of 1280x1024.
