I am building a small Ubuntu box made for our clients to listen to an audio stream. At startup, I have scripts that start the audio stream, then locks the screen so clients can't change any settings. It works flawlessly.
However, if a client has to shut down the box, they can't. Note this is a headless unit, no monitor, keyboard, or mouse. It will ONLY be used to play streaming audio. I need for the client to be able to safely shutdown the unit by pressing the power button. But, when the power button is pressed, ubuntu asks for the user password. Is there a way to just make the system shutdown without entering a password?
