Recently we found this excellent quick start guide by Kenn Ranous which shows how to set up various RTL-SDR related software programs on (Debian) Linux. The guide shows how to install the drivers, how to install and set up GQRX, CubicSDR, dump1090, Virtual Radar Server, QSpectrum Analyzer and SDR Trunk.
If you are struggling with getting an RTL-SDR to work on a Linux system then this should be a very good starting point.
The guide can be found on Kenn’s blog at https://ranous.wordpress.com/rtl-sdr4linux.
