raspi-config is the Raspberry Pi configuration tool written and maintained by Alex Bradbury. It targets Raspbian.
You will be shown
raspi-config on first booting into Raspbian. To open the configuration tool after this, simply run the following from the command line:
sudo is required because you will be changing files that you do not own as the
You should see a blue screen with options in a grey box in the centre, like so:
It has the following options available:
Raspberry Pi Software Configuration Tool (raspi-config) Setup Options 1 Expand Filesystem Ensures that all of the SD card storage is available to the OS 2 Change User Password Change password for the default user (pi) 3 Enable Boot to Desktop/Scratch Choose whether to boot into a desktop environment, Scratch, or the command line 4 Internationalisation Options Set up language and regional settings to match your location 5 Enable Camera Enable this Pi to work with the Raspberry Pi camera 6 Overclock Configure overclocking for your Pi 7 Advanced Options Configure advanced settings 8 About `raspi-config` Information about this configuration tool <Select> <Finish>
Moving around the menu
down arrow keys to move the highlighted selection between the options available. Pressing the
right arrow key will jump out of the Options menu and take you to the
<Finish> buttons. Pressing
left will take you back to the options. Alternatively, you can use the
Tab key to switch between these.
Note that in long lists of option values (like the list of timezone cities), you can also type a letter to skip to that section of the list. For example, entering
L will skip you to Lisbon, just two options away from London, to save you scrolling all the way through the alphabet.
What raspi-config does
raspi-config aims to provide the functionality to make the most common configuration changes. This may result in automated edits to
/boot/config.txt and various standard Linux configuration files. Some options require a reboot to take effect. If you changed any of those,
raspi-config will ask if you wish to reboot now when you select the
If you have installed Raspbian using NOOBS, the filesystem will have been expanded automatically. There may be a rare occasion where this is not the case, e.g. if you have copied a smaller SD card onto a larger one. In this case, you should use this option to expand your installation to fill the whole SD card, giving you more space to use for files. You will need to reboot the Raspberry Pi to make this available. Note that there is no confirmation: selecting the option begins the partition expansion immediately.
Change user password
The default user on Raspbian is
pi with the password
raspberry. You can change that here. Read about other users.
Enable boot to desktop or Scratch
You can change what happens when your Pi boots. Use this option to change your boot preference to command line, desktop, or straight to Scratch.
Internationalisation Options and press
Enter to be taken to a sub-menu containing the following options:
Select a locale, for example
Select your local timezone, starting with the region such as
Europe, then selecting a city, for example
London. Type a letter to skip down the list to that point in the alphabet.
Change keyboard layout
This option opens another menu which allows you to select your keyboard layout. It will take a long time to display while it reads all the keyboard types. Changes usually take effect immediately, but may require a reboot.
In order to use the Raspberry Pi Camera Module, you must enable it here. Select the option and proceed to
Enable. This will make sure at least 128MB of RAM is dedicated to the GPU.
It is possible to overclock your Raspberry Pi's CPU. The default is 700MHz but it can be set up to 1000MHz. The overclocking you can achieve will vary; overclocking too high may result in instability. Selecting this option shows the following warning:
Be aware that overclocking may reduce the lifetime of your Raspberry Pi. If overclocking at a certain level causes system instability, try a more modest overclock. Hold down `shift` during boot to temporarily disable overclock.
Old TV sets had a significant variation in the size of the picture they produced; some had cabinets that overlapped the screen. TV pictures were therefore given a black border so that none of the picture was lost; this is called overscan. Modern TVs and monitors don't need the border, and the signal doesn't allow for it. If the initial text shown on the screen disappears off the edge, you need to enable overscan to bring the border back.
Any changes will take effect after a reboot. You can have greater control over the settings by editing config.txt.
On some displays, particularly monitors, disabling overscan will make the picture fill the whole screen and correct the resolution. For other displays, it may be necessary to leave overscan enabled and adjust its values.
Set the visible name for this Pi on a network.
Change the amount of memory made available to the GPU.
Enable/disable remote command line access to your Pi using SSH.
SSH allows you to remotely access the command line of the Raspberry Pi from another computer. SSH is disabled by default. Read more about using SSH on the SSH documentation page. If connecting your Pi directly to a public network, you should not enable SSH unless you have set up secure passwords for all users.
Enable/Disable the use of Device Tree. Read more about Device Trees config on the Device Trees documentation page.
Enable/Disable SPI interfaces and automatic loading of the SPI kernel module, needed for products such as PiFace.
Enable/Disable I2C interfaces and automatic loading of the I2C kernel module.
Enable/Disable shell and kernel messages on the serial connection.
Force audio out through HDMI or a 3.5mm jack. Read more on the audio configuration documentation page.
Update this tool to the latest version.
Selecting this option shows the following text:
This tool provides a straightforward way of doing initial configuration of the Raspberry Pi. Although it can be run at any time, some of the options may have difficulties if you have heavily customised your installation.
Use this button when you have completed your changes. You will be asked whether you want to reboot or not. When used for the first time, it's best to reboot. There will be a delay in rebooting if you have chosen to resize your SD card.
