Breathing light: edit /etc/mce/mce.ini (have a backup first; added values in BOLD): ... [LED] # List of patterns for the LED functionality # # A list of all pattern names that should be configured LEDPatterns=PatternPowerOn;PatternPowerOff;Pattern Communication;PatternCommunicationAndBatteryFull;P atternBatteryCharging;PatternBatteryChargingFlat;P atternBatteryFull;PatternDeviceSoftOff;PatternDeviceOn CombinationRules=CombinationCommunicationAndBatter yFull ....

I have used the value from PatternBatteryCharging; can be modified accordingly. PS: for breathing light is no need to have "LED Event Notifier" and "Inception" installed. For extra LED notifications above programs are (still) mandatory.
