  1. Closing an interactive non-login terminal (such as a terminal window in Gnome or kde) won't send a SIGHUP signal. You can change that behavior in other type of shell (via a huponexit option) but not in interactive non-login term's. See https://askubuntu.com/a/685291/798765 for more details on huponexit ;)
