Thanks for your answer, and you are right, as another person on here had 
me look at the man for xset, and it turns out X by default will blank 
the screen after 10 minutes of inactivity. According to the same person, 
while attempting to turn screen saving off, my use of the gconf editor 
to change some settings related to screen saving, somehow stopped 
gnome-screensaver from overwriting the X server's default setting of 10 
minutes at boot up, and that started the problem.

I'm not sure which setting in gconf-editor caused it, as I haven't had 
time to look through it yet again, but by looking through man xset, I 
was able to determine the command to use to set X's blank screen setting 
to 0 which disables it.

I'm a programmer too, and believe software should be written to 
co-operate with the system it's on. In this case evidently, gconf-editor 
overrides something which gnome-screensaver depends on to enforce it's 
settings, which I had set to not use any blanking. Since I didn't know 
that X had a setting to blank the screen as well, I spun my wheels for 
nearly two days trying to find out why the screen saver wouldn't shut 
off, and it turned out to not even be the screen saver. 8-)
