fedora 17: disable blank screen

i read a lot of people using recent releases of fedora (15-17) seeking how to disable blanking of screen because Brightness and Lock settings dialog only offers a max of 1 hour before it turns off the screen.

on boot, my fedora 17 has the ff. xset screen saver and power management settings:
# xset -q

i tried a lot of things (even installing the presentation mode extension in gnome, but it would require you to click on the presentation toggle everytime you reboot).

my final solution was to do the ff:

1. disable launching of the screen saver application in gnome

# gnome-session-properties

2. create a script that does the ff in xset:
 a.) disable blanking of screen
      # xset s noblank
 b.) turn of screen saver
      # xset s off
 c.) disable power management

      # xset - dpms

my final xset settings show:

#xset -q

i tested this in fedora 17 (beefy miracle) on a laptop and a couple of desktops.
