 1. Setup autostarting of desktop applications:
     1. (Note) Desktop applications are applications with `<name>.desktop` files. These applications may be autostarted using a tool like `dex`, following the XDG Autostart spec.
     1. (Note) To enable autostarting for a desktop application, find/create a `.desktop` entry file for it in `/etc/xdg/autostart` (system) `~/.config/autostart` (user). A simple method is to find the entry in e.g. `/usr/share/applications/` (system) or `~/.local/share/applications/` (user), then symlink it into the appropriate autostart directory (e.g. `ln -s /usr/share/applications/discord.desktop ~/.config/autostart`).
