Change automaticaly the Linux keyboard layout on my laptop when an external keyboard is connected/disconnected

gistfile1.txt

Plug your external keyboard and enter the following command line to get the vendor/product id:

    # lsusb 
    Bus 002 Device 065: ID 05ac:024f Apple, Inc. Aluminium Keyboard (ANSI)

For example, my Keychron keyboard is detected as an Apple keyboard with vendorid=05ac and productid=024f

Create the following scripts:

    # sudo vi /etc/udev/rules.d/10-keyboard-plug.sh
    ACTION=="add", ATTRS{idVendor}=="05ac", ATTRS{idProduct}=="024f", ENV{XKBMODEL}="pc105", ENV{XKBLAYOUT}="us"
    
    # sudo vi /etc/udev/rules.d/10-keyboard-unplug.sh
    ACTION=="remove", ATTRS{idVendor}=="05ac", ATTRS{idProduct}=="024f", ENV{XKBMODEL}="pc105", ENV{XKBLAYOUT}="fr"

Note: in order to get keyboard layout configuration, use the *setxkbmap -query* command.
