Allegedly, on or about 6 January 2018, Max Pyziur sent:
everytime I login to my computer, Skype is automatically active.
Is there a way of disabling this feature?
What's your desktop?
If yours saves the session on exit, and Skype was running, it would run
again next time you login. If you quit Skype, before exiting, it
oughtn't to start again at next login.
There are session preferences for things to always start up.
In Mate: System menu, Preferences item, Personal sub-menu, Startup
applications. Or, "mate-session-properties" on the command line.
Gnome had something similar, dunno what the new Gnome has, but the
command may be the same (e.g. gnome-session-properties).
KDE will have something similar.
Application' .desktop files copied into /etc/xdg/autostart/ will run
at startup: https://developer.gnome.org/autostart-spec/
I can't recall whether there's a more generic session starter that'd
apply to all the desktops (though xdg is kind-of in that direction).
If you go through your settings for Skype, you may find a startup at
[tim@localhost ~]$ uname -rsvp
Linux 4.13.16-202.fc26.x86_64 #1 SMP Thu Nov 30 15:39:32 UTC 2017 x86_64

There is no point trying to privately email me, I only get to see
the messages posted to the mailing list.
If you are not the intended recipient, why are you reading their email?
