Using systemsetting GUI, I removed a `key`:

[AC][DimDisplay]
idleTime=540000

Also, my kde-plasma-framework... might be more up to date.

Who knows. In any case the above script, which leaves much to be desired, is 
now working.

So, with it running in a terminal, you can do: Ctrl-Alt-L, and ta-da, the 
screen turns of a few seconds later.
And when you unlock, the default behavior is restored.
