This is another “Note to self” post.
For a workshop I will present at the Agile Testing Days 2022, I’ve set up a backup computer, in case folks don’t have Ruby installed on their machine already, or don’t get it installed within the available time slot.
The Raspberry itself had already worked … with some keyboard back in 2017 (when I used it in a ½ days tutorial at the same conference). But now, I connected a Mac keyboard to it, one with a German layout – including the umlauts. Getting the configuration to work well enough was surprisingly hard.
The existing keyboard configuration didn’t work very well, since it expected an international layout, meaning that the key cap labels weren’t always correct. Or the printed key wasn’t, depending on your perspective.
Setting it up using the GUI application that comes with RaspbianOS didn’t work so well either: for some configuration settings the keyboard stopped reacting completely. Yay! I learned another way how not do do it. 🤣
In the end I used the terminal raspi-config:
sudo raspi-config
to try all variations of (non-japanese) Apple keyboards with the corresponding German layouts and variants.
In the end I settled with this configuration, as it is stored in /etc/default/keyboard on the Raspi:
# KEYBOARD CONFIGURATION FILE
# Consult the keyboard(5) manual page.
XKBMODEL=apple
XKBLAYOUT="de"
XKBVARIANT=
XKBOPTIONS="lv3:ralt_switch,terminate:ctrl_alt_bksp"
BACKSPACE="guess"
