Apple USB keyboard wired

It was a hardware problem: three arrow keys were not working on the Apple KB.

 Plugged PS/2 keyboard  into mouse port.

#. Not true:

These are great keyboards but support under Ubuntu is janky.

https://2e0pgs.github.io/blog/sysadmin/2021/04/03/apple-keyboard-ubuntu/

 

You can add the following lines to: /etc/modprobe.d/hid_apple.conf

$ cat /etc/modprobe.d/hid_apple.conf
options hid_apple fnmode=2
options hid_apple iso_layout=0

Then run sudo update-initramfs -u -k all and sudo reboot

 

mac_hid or hid_apple

 Turns out hid_apple was renamed to applespi.

echo 2 | sudo tee /sys/module/applespi/parameters/fnmode
