Automatically suspend machine after screen lock is active

Help
1

When I plug in the power supply while the notebook is in sleep mode, it turns on and stays on for 45 Minutes, as configured in the power saving settings.

Is there a way to configure KDE Neon to get back to sleep in a shorter time period while the lock screen is active?

I have a little script that sets custom dim screen / screen off / suspend timeouts.

It takes modes (--bat, --ac, --lowbat) and timeout values for dim_screen, screen_off and suspend (in that order) in seconds.

To have shorter timeouts I when locked have the script setup like this:

System settings > Notifications > Application-specific settings (Configure) > Screen Saver > Configure events > Run command

  local time=$1

  local time_ms=$time
  if [[ $group != "DPMSControl" ]]; then
    ((time_ms *= 1000))
  fi
    if ((time > 0)); then
      echo "  ${group}: ${time}s"
      kwriteconfig5 --file "$conf_file" --group "$mode" --group "$group" --key idleTime "$time_ms"
    else
      echo "  ${group}: disabled"
      kwriteconfig5 --file "$conf_file" --group "$mode" --group "$group" --key idleTime --delete
    fi
}
