[mythtvnz] DPMS? How to make it stick?

[David Moore]

Aargh! Once again an upgrade has broken something. Screensaver used to 
work with MythTV for me but not after upgrading to 0.25. Seems DPMS is 
now the way to go. So I added this to my xorg.conf but it doesn't seem 
to be recognised at boot.

Section "ServerFlags"
	Option	"StandbyTime"	"2"
	Option	"SuspendTime"	"3"
	Option	"OffTime"	"4"
EndSection

I have confirmed DPMS does work if I manually do "xset -display :0 dpms 
120 180 240" from the CLI. (Grr! HATE the fact that xset uses seconds 
and xorg.conf uses minutes.)

I know Ubuntu is making xorg.conf less relevant over time but I can't 
find what is over-riding or ignoring my serverflags entries. Anybody 
know how to make this work, i.e., how to get X to take the customised 
timeouts at boot? I suppose I can use xset in a startup script but that 
seems like a bit of kludge to me.
