The following line does succeed in conveniently setting `dpms` timer.

`kwriteconfig5 --file powermanagementprofilesrc --group AC --group DPMSControl --
key idleTime 60; qdbus org.kde.Solid.PowerManagement /org/kde/Solid/
PowerManagement org.kde.Solid.PowerManagement.refreshStatus`

And again, kwin-wayland seems more consistent than its x11 counterpart in the 
matter of turning the screen off, so, so far, the whole operation is far less 
painful than it was with x11 version.

See: https://bugs.kde.org/show_bug.cgi?id=340342
for the command line.
