I set the DPMS settings in:
Configure Desktop (Personal Settings) -> General tab -> Display (under Computer
Administration heading) -> Power Control
There I set everything (Standby after:, Suspend after:, Power off after:) to 15
mins. The only real important one is Standby. They could all be set to
different times, but Standby is the one that matters.
Then, back to Configure Desktop (Personal Settings) -> General tab -> Desktop
(under Looks & Feel heading) -> Screen Saver
I put a check mark in "Start automatically" and set it to one minute more than
my Standby setting from above. So in this case, it's set to 16 minutes.
This means the screensaver never comes on, but I can still use the "Require
password to stop" feature, which is found on the same screen. I set that to 1
second.
So now my screen turns off completely (even the backlight).
I also tested a couple other things. Manually turning on the screensaver by
clicking on the padlock icon on the right of my taskbar also prevents DPMS from
working.
For some reason, once my monitor turns off via DPMS (after 15 minutes), when I
press a key on my keyboard to awaken it, the screensaver is already running and
it asks me for my password, even if it hasn't been 16 minutes yet. It seems
like the DPMS "Standby" setting also locks the screen at the same time. I would
consider this "expected behaviour", but I wonder if it's part of the reason why
DPMS is being defeated by an already-running screensaver? Maybe the call to
lock the screen by DPMS is failing because the screen is already locked, and so
PowerDevil (the KDE Power Management app) doesn't proceed beyond this point?
I'm only guessing here, I'm no programmer.
