Ubuntu – Key ‘@’ (Keycode 49) and key ‘<' (keycode 94) are inverted on macbookPro keyboard

keyboardkeyboard-layoutmacbook proxkb

I am running Ubuntu 16.10 on a MacbookPro and keys 49 and 94 are inverted… I resolved this problem with xmodmap, but this won't apply permanently. After some research I found xmodmap is no longuer use by Ubuntu but xkb instead. So I searched in the configuration of xkb and I found in the config file /usr/share/X11/xkb/keycodes/macintosh this lines :

xkb_keycodes "badmap" {
    <TLDE> =  94;
    <LSGT> =  49;

xkb_keycodes "goodmap" {
    <TLDE> =  49;
    <LSGT> =  94;

This is exactly my problem, this two keys are inverted. So I wondering if I can't change my layout configuration with the param badmap.

The ouput of setxkbmap -query -v 10

I accidentally stumbled upon this patch, which led me to the solution:

Open /etc/default/keyboard for editing and set:


At next reboot those keys will be switched.
