I know that I can't with the default programs (there was a way for Luna, but doesn't work with Freya), but does anyone know how I can make a specific sound file play at the login with 3rd party programs or scripts? I know most of you think it's a waste of time and is unnecessary, but I really want it. And that's part of the reason we came to linux to the first place, isn't it? It being a flexible system in which you can customize to your liking?
