Raspberry Pi Tip: Change keyboard layout

Published August 16, 2013 by doug

If you’re in the US like me and you start coding on your Raspberry Pi, you might quickly realize that when typing the pound key # you get the currency symbol: £

This is because the Raspberry Pi defaults to the British Keyboard layout. To change this, as sudo edit the file:

etc/default/keyboard

Change XKBLAYOUT=”gb” to XKBLAYOUT=”us”

# KEYBOARD CONFIGURATION FILE

# Consult the keyboard(5) manual page.

XKBMODEL="pc105"
XKBLAYOUT="us"
XKBVARIANT=""
XKBOPTIONS=""

BACKSPACE="guess"

Then restart your Pi.
