Notes – Raspberry Pi

Installing / Using Raspberry Pi Raspbian

Download image file from :

Format SD card with SDFormatter w/ Format Size Adjustment set to ON

Imaged SD card with Win32DiskImager

Username/Password for Raspbian
pi / raspberry

Checked the size of partitions with parted
> sudo parted -l

Expanded Filesystem with raspi-config
> sudo raspi-config
option 1


Install gqrx Software Defined Radio Package
> sudo apt-get install gqrx-sdr

Running gqrx failed with “gqrx: cannot connect to X server”

Removed gqrx
> sudo apt-get purge –auto-remove gqrx-sdr

Check linux version
> cat /proc/version

Install software-properties-common to use “add-apt-repository”
> sudo apt-get install software-properties-common

It appears gqrx is processor intensive, therefore the Raspberry Pi B+ is not a good platform
for this application


To run a GUI on Rasbian

> sudo tasksel
select enviroment with spacebar {I chose LXDE}
press enter
tasksel: apt-get failed (100)

I tried selecting “Debian desktop enviroment” and “LXDE”
same error

same error selecting “xfce”

Install LXDE with apt-get

> sudo apt-get install LXDE


a gui is not recommended as it’s very slow

to uninstall LXDE , sudo apt-get purge –auto-remove LXDE , doesn’t work
I could further remove all packages related to LXDE, however I’m not concerned with space at
this time

Setup Pi to boot into console on startup

run raspi-config
> sudo raspi-config
select boot options [3]
select B2 Console Autologin
