Other Help Topics :: Nothing on screen
If your speaking of the screen blanking mode..
(where monitor goes black after a time, unless mouse is moved)
For the GUI, type this into your .xinitrc ABOVE the fluxbox line.
xset s off s noblank
For the CLI/command line blanking ( No X desktop ) try adding
this to your bootlocal.sh file.
setterm -term linux -blank 0 >/dev/tty1
This should defeat any screen-saving features on your box.
