	Run the command lsusb if you have your NESDR ~~SMArt~~ plugged into your Ubuntu computer. This will list all of the USB devices attached to the computer. If things are working as they should be, you will see the NESDR SMArt listed as: RealtekSemiconductor Corp. RTL2838 DVB-T.		Run the command:
			lsusb

			RealtekSemiconductor Corp. RTL2838 DVB-T.
	The DVB-T is the important part, because it means that the operating system has recognized the device and loaded, what it believes to be, the correct driver.

	We need to remove those modules (drivers) and load the appropriate ones using the device as an SDR. We start by “blacklisting” the default drivers. This is done by editing the file/etc/modprobe.d/blacklist-dvb.conf. Add the following line to blacklist this file.

	What that does is disallow the default module (driver) to load. Now we need to tell it to load the driver we want.

	~~Add~~ GNU radio to ~~that; I recommend~~ to ~~download~~ it via CLI with: sudo apt-get install gnuradio gqrx~~-sdr~~		However you will also need GNU radio to run Gqrx. Therefore it is recommended to simply install it via CLI with:
