The problem is probably that the video devices on your linux box are
either in use, or you don't have permissions to access them. If either
of those is true, vic will default to transmitting X11 screen captures.
This is a common problem when one person logs in to the console, and
another person tries to run the AG software, because the devices will be
owned by the first person and closed to everyone else.
