Q:How to enable DPMS at startup ?

Hi,
That's a thing I want to know for a long time. The xset command works 
when I launch it in a terminal, but, not automatically. I've put it in :
/etc/X11/xfce/xinitrc
/etc/X11/xinitrc
/etc/X11/Xsession

The DPMS delays are still the default ones.
I'd like to make them active in X, whatever is the window manager. Is it 
possible ? Why it doesn't work (or how can I know why ? Is there a log?)
Otherwise, how can I do it in xfce3 (under LinuxFreeduc based upon 
KNOPPIX/Debian)
