Change keys for Apple keyboard on Linux
I use an Apple keyboard at my workstation. However, I was bothered by the layout of certain keys under Linux. So I did a little research and set out to change this myself.
The first thing we need to do is install evtest
sudo apt install evtest
sudo dnf install evtest
With this we can display different values of pressed keys in the command line.
After the installation we start evtest simply in the command line with
Now you look for the matching event number to your keyboard
Select the device event number:
and type the number and press Enter
Now it’s time. Press the key on your keyboard you want to change. In this example I decide to use the Enter key.
Event: time 1668908629.343883, type 4 (EV_MSC), code 4 (MSC_SCAN), value 70028
Event: time 1668908629.343883, type 1 (EV_KEY), code 28 (KEY_ENTER), value 0
At the end of the first line we are interested in the number after value.
Create a new file at
sudo nano /etc/udev/hwdb.d/70-keyboard.hwdb
and make your change there.
This is my example file how I set it up for me
evdev:name:Magic Keyboard:* # name, the same as in event number # KEYBOARD_KEY_value=function # function, 2nd line of Event KEYBOARD_KEY_C00B8=delete # map EJECT to Delete KEYBOARD_KEY_700E0=leftmeta # map ctrl to leftmeta KEYBOARD_KEY_700E2=leftalt # map alt to leftalt KEYBOARD_KEY_700E3=leftctrl # map cmd to leftctrl
Update the Hardware Database
sudo udevadm hwdb –update
Make it directly avaiable (XX stands for your right event number)
sudo udevadm trigger /dev/input/eventXX
