I know this has been asked multiple times. I have tried multiple things, however nothing I seem to do stick. I am trying to disable the screen saver/screen blanking on Lubuntu 14.04. I've tried the following in rc.local, but nothing seems to actually disable it:
xset -dpms xset s off xset -dpms; xset s off
setterm -blank 0 -powerdown 0 echo -ne "\033[9;0]" >> /etc/issue

light-locker lies liberally. Even with it set to disabled, even with it explicitly telling me that locking was being handled by Xfce Power Manager, it still jumped in and locked the screen after resume from suspend.
Solution: sudo apt-get -y remove light-locker
And get on with your life.
