I'm trying running the following in a terminal, and then locking the screen 
with Ctrl+Alt+L:

#! /bin/bash

dbus-monitor --session "type='signal',interface='org.freedesktop.ScreenSaver'"

  while read x; do
    case "$x" in
      *"boolean true"*) 
        echo SCREEN_LOCKED;
        kwriteconfig5 --file powermanagementprofilesrc --group AC --group 
DPMSControl --key idleTime 60;
        qdbus org.kde.Solid.PowerManagement /org/kde/Solid/PowerManagement 
org.kde.Solid.PowerManagement.refreshStatus
        ;;              
      *"boolean false"*)
        echo SCREEN_UNLOCKED;
        kwriteconfig5 --file powermanagementprofilesrc --group AC --group 
DPMSControl --key idleTime 600;
        qdbus org.kde.Solid.PowerManagement /org/kde/Solid/PowerManagement 
org.kde.Solid.PowerManagement.refreshStatus
        ;;              
    esac
  done
