yes, I have tried the xset dpms flags option
eg. 'xset dpms 1201 1801 2401'

and these stay set until i reboot or kill X
but I _think_  I have seen a stray "dpms-like suspend" occur
at least once even with those settings.
So it still looks to me like some other system control.

I am using gnome; so maybe gnome power manager
is doing something here.
My system is a desktop not laptop.

Do you have any more info as to just how in your case
xset dpms was fighting with gnome power manager?

As near as I can tell the gnome power manager and gnome
screensaver implement some kind of gnome specific replacement
for the low level "xset" type operations, yet they don't
bother disabling the low level xset settings even when they
conflict with the gnome settings, so you wind up with both of
them taking effect at unexpected times. There have also
been a fantastic number of bugs with the gnome power
manager which would do things like trigger screen
blanking even though you just typed something about 3
seconds ago (even if you thought you had disabled
the gnome power manager). I tend to yum erase
gnome-power-manager these days and add startup entries
to run xset commands to get more reliable screen
blanking when I actually expect it to happen.
