The Intel Compute Stick comes with Ubuntu 14.04 LTS preloaded, running the full-fat Unity interface. In an effort to minimise RAM usage (to keep as much available for STF as possible), I've replaced Unity with lubuntu-desktop (LXDE) and removed a whole bunch of default packages which aren't relevant. If you choose to replace Unity with something lighter (such as Lubuntu/LXDE), it's probably a good idea to run `sudo apt-get clean` (and/or remove some unwanted packages) after installing lubuntu-desktop but before logging out of your Unity session, so that there's some storage space free; my Compute Stick ran out (a decent chunk of the already tiny 8GB is taken up by a recovery partition, which I may back up and then remove), resulting in neither Unity nor Lubuntu/LXDE wanting to start - both just showed the wallpaper after login, with no other UI, and wouldn't respond to anything. If you do get stuck in that state, try dropping to a console (ctrl+alt+F1) and running `sudo apt-get clean` in order to free up some space before you log in.
