To turn off screen blanking of the screen :

- edit your autostart and add

xset -dpms &
xset s noblank &
xset s off &

- if you have an xorg.conf file, edit it as root and add in the section "ServerLayout":

Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"

and in the section "Monitor":

Option "DPMS"

where you can alternatively just add:

Option "NODPMS"

without using the  ServerLayout options

Some systems prefer this in the 'Device Section

Option "DPMS" "off"
