Using raspi-config
The
raspi-config
tool is a basic utility that is included in each copy of Raspbian. It is
a menu-based GUI that enables you to easily modify your Raspberry Pi settings.
To run
raspi-config
, type
sudo raspi-config
on the command line.
The
raspi-config
tool offers the following options:
•
Expand filesystem
: This option will resize the OS to use all of the available SD
card space.
•
Change user password
: This will prompt you for a new password for the user Pi.
•
Enable boot to desktop/Scratch
: This allows you to switch between booting to
the command prompt, Scratch, or the desktop.
•
Internationalization options
: This option allows you to change your time zone
and your keyboard layout.
•
Enable camera
: If you have the Raspberry Pi camera module, check this to yes.
•
Add to Rastrack
: This option enables other people to know your Pi's location.
•
Overclock
: You can change your Raspberry Pi's speed here.
•
Advanced options
:
There are many advanced options in
raspi-config
which are explained as fol-
lows:
◦
Overscan
: If you see black bars on your monitor, or your screen might be
a little off; use overscan to correct it.
◦
Hostname
: This sets your Raspberry Pi's network name (Default: rasp-
berrypi).
◦
Memory split
: This changes the memory available to the GPU, while
leaving the rest to your applications. The minimum is 16 MB.
Note
If you have Model A or A+ the maximum split can be 192 MB, and on
Model B or B+, you can go to 448 MB. I wouldn't recommend going high-
er than 128 MB, as you want to devote enough RAM to Linux.
◦
SSH
: This option allows you to remotely connect to your Raspberry Pi.
◦
SPI
: This enables autoloading of the SPI module. Your hardware should
let you know if you need this.
