Well, that was interesting reading. Thank you for your answer, but
Rashkae had already pointed me at man xset, and I have now learned how
to disable the blanking which was driving me crazy.
The problem was actually that X has a default setting of 10 minutes for
blanking the screen, which gnome-screensaver usually overwrites on boot
up. Somehow, while attempting to disable screen saving with
gconf-editor, I managed to disable this overwriting, and X took over and
began blanking the screen after ten minutes.
I have now used the command "xset s off" to disable the timeout value,
and the screen no longer blanks after ten minutes. I haven't re-booted
yet, but if it blanks again after a re-boot, I will write a short bash
script to disable it, and add that to the Session Manager so it gets ran
at log on. Problem solved!
