[Conversations get confusing when you put answers before the questions]

Thanks for your help. I've been playing more attention to when this problem
occurs and when it doesn't. In fact it's more subtle than I realized at first.

When I first start up the X server dpms does manage to shut down all three
monitors whenever it screensaves.

When I run mplayer it turns off screen saving. I guess that's a good thing
since it does suck when the screen saver kicks in in the middle of a movie.
And the mouse and keyboard are likely to be idle for a long time while the
movie is playing.

When mplayer finishes it reenables dpms. But from that point on things don't
work properly any more. Sometimes nothing screen saves (perhaps when mplayer
crashes?). Then even when I try to turn on screen saving with xset I can't get
it to work on the non-primary monitors. Even if I run "xset force off" on one
of the secondary screens it's still just the primary monitor that turns off.
