John Wiseman has been working on a cool old-school retro styled aircraft ADS-B radar that runs entirely within a terminal window. So no GUI desktop should be required. The project, called "coole-radar", is available as open source code on GitHub.
It takes decoded ADS-B data via a Virtual Radar Server webpage, so it should be fairly easy to set up together with an RTL-SDR and dump1090 that feeds Virtual Radar Server. The latest version displays a radar screen with decay-like effect, a list of currently detected aircraft, and a pixelated screen of the aircraft image downloaded from the internet.
