I want to set up a Kiosk session that only runs Mixxx in order to decrease vulnerabilities of my data and system at a party I'm hosting. I'm thinking of creating another user (call it DJ), so when I log in into DJ, the only thing available is Mixxx. I know that a guest user is an option but any user still has full control of that session.
I've seen many posts about this in askUbuntu but either they are specifically related to a web-browser kiosk or too advanced for me (the closest one would be this, but it mentions a .desktop file and a shell script without discussing it).
I'm using Xubuntu 14.04.02.
