Screensaver issues

Hi I am new to Debian.. I am new to Debian as of yesterday.

I am having trouble with my screen... My screen has quit turning off
after 20 min. 

Here is the output of xset -q

Can someone please tell me how to get my screen to turn off again?

I tried asking in the #Debian IRC room and they told me to run xset man

I looked at xset man but I dont understand the commands to force my
screen to turn off after 20 min. 


Thank you,
Chris
