For the longest time after about 5 minutes my screen would blank out. Now the screen will go blank after 5 minutes but then 2 seconds after that it will light up white and keep the laptop backlighting on. I didn't change any settings to my knowledge it just happened randomly after powering it on one day and has occurred since then.

I wish to resort back to blanking the screen out completely since I leave this computer on all the time and it's hard to sleep with a huge white light all the time.

xset dpms force off just yields me:

xset:  unable to open display ""

You need to tell xset which display to use:

export DISPLAY=:0
xset q

Try vbetool instead xset:

sudo vbetool dpms off

It's works fine for me.
