I started by following these instructions to clone, build, and install MalcomRobb’s fork of dump1090. After following the instructions (and blacklisting the dongle from being used by the OS), I was able to start seeing aircraft:

In the screenshot above, you can see the flight track I captured of United Airlines flight 1239, flying from Houston, TX to Vancouver, BC.
