This is both a comment and a question,
Every Linux distribution I have used includes cheese as the default webcam program and almost always it does not work and the program cannot be uninstalled because other programs rely on it. Why not install a program such as Simple UVC Viewer as the default? I know it can be installed from the software center and I always do, but I find it odd that a program that is broken is always the default.
That being said, thank you very much for a top-notch OS, Antergos is the best distro I have used in a long time.
Have a good day, cheers.
