Did you do the two echo's?
I found the original email and it had the following comments:
setterm -blank 5 -powersave on # dpms on
echo -en "\033[9;8]" # suspend after 10 min
echo -en "\033[14;10]" # off after 30 min
I can't find any documentation to explain the values but I remember
playing with them and it's the echo statements that tell the monitor
to go to sleep.
