I personally needed a light editor, possibly not related to KDE or Gnome (which generally means plenty of packages installed).
I found Leafpad, which does the job. So, I generally install it as well:

With these packages, you should have a very light X environment, with xterm, a basic text editor and a basic bar with workspaces and current time.
Super basic. Super light. Super Functional. 🙂

I liked also to customise the menu, because the default one was too messy for me.

To do this, create a .blackboxrc file if not present in your home directory.
After, just add the following:

session.menuFile: ~/.blackbox/blackbox-menu

Of course, make sure to have also a folder called .blackboxand the file blackbox-menu customised like this one:

[begin] (MinimalMenu)
[exec] (XTerm) {xterm}
[exec] (LeafPad) {/usr/bin/leafpad}
[submenu] (Blackbox)
[config] (Configuration)
[submenu] (Styles)
[stylesdir] (~/.blackbox/styles)
[sep]
[stylesdir] (/usr/share/blackbox/styles)
[end]
[workspaces] (Workspaces)
[sep]
[reconfig] (Reconfigure)
[restart] (Restart)
[exit] (Exit)
[end]
[end]

Otherwise, you can always start using a copy of the default one:

cp /etc/X11/blackbox/blackbox-menu ~/.blackbox/blackbox-menu

Here you go! Enjoy! 😉
