As near as I can tell, you need to use all of belt, suspenders, duct tape,
and bailing wire to really turn off screen blanking.

1st check the screensaver. You may actually have two menu entries for screensaver,
one for gnome, and the other for the tradition X11 screensaver. Make sure they
are both turned off.

2nd check the power management options and tell it to never turn anything off.
If it is a laptop, you may need to fiddle both the on AC and on battery pages.

3rd run gconf-editor (which you may have to install) and go to the
key for /apps/gnome_settings_daemon/screensaver and uncheck the
option to start the screensaver.

4th write a bash script that runs these commands:

xset s off
xset dpms 0 0 0
xset -dpms

and add it to your startup scripts (make sure you
chmod it to be executable).

If, after doing all that, the screen still blanks, then there probably
is something in the BIOS you need to disable as well.
