Sounds more like a screen-saver is kicking in.


I have these lines in /etc/rc.d/rc.local

/usr/bin/xset s noblank
/usr/bin/xset s noexpose
/usr/bin/xset s off
/usr/bin/xset s powersave off
/usr/bin/xset -dpms
/usr/bin/xset --display :0.0. q

Not sure which of them actually does the trick. I think it is the 
'-dpms' entry, as the others always report not being able to find a 
screen. (I think that that is because these are run before the login to 
X. and should be afterwards.)

In addition, in xorg.conf I have

Section "ServerFlags"
     Option         "DPMS" "true"
EndSection

And  in 'Section "Monitor"'
    Option         "DPMS" "true"
