[GTALUG] xset and DPMS

I have a new monitor that's notoriously prone to burn-in ... This is an
IPS monitor, and none of us thought burn-in even existed anymore. But I
don't think this is quite the same as what it was with plasmas - in this
case, I think the "burn-in" lasts a matter of hours rather than being
permanent? I'm not sure because I don't care to experiment. Yes, I knew
this before I bought the monitor, but it's other advantages outweighed this
problem. And yes - it's an incredibly stupid problem to have with a
monitor where things stay in the same place for hours, months, and
sometimes years.
So one of the computers I attach to it (a middle-aged Chromebook) has
Debian stable installed, and I'm running Fluxbox on it. I use this:
$ xset +dpms
$ xset -q
... # DPMS confirmed on
$ xset dpms 240 1800 1800
To turn on DPMS and set the time-outs. But ... every time the screen
blanks, it apparently disables DPMS again. This can be confirmed with
'xset -q' again, which now says "disabled." Is this a system setting or
service, Debian or Fluxbox or something else that resets itself every time
DPMS is activated? I have no such problem under Fedora 26/Openbox.
