There two main paths to look for entries to autostart:
/etc/xdg/autostart – called system-wide and most of the application will place files when they are installed.
[user’s home]/.config/autostart – user’s applications to start when the user logs in .
There is a security problem here, which is sometimes installing a package will place an autostart file there because the maintainer decided it is important but the package might be just a dependency and the next time the user logs in unwanted program might execute and open ports!
