# My keyboards are id 10 (laptop integrated) and id 17 (external keyboard). 

# Now, set my external keyboard to be Swedish layout, and my internal to Dvorak:
$ setxkbmap -device 17 se
$ setxkbmap -device 10 dvorak

# Done!

Well, it did not take long, I have tried myself doing a configuration that allows me changing between "us" and "us intl" in the internal laptop keyboard, and between "es", "us" and "us intl" for external USB keyboards. It works like a charm:

Section "InputClass"
        Identifier "evdev keyboard catchall"
        MatchIsKeyboard "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
        Option "XkbLayout" "es,us,us"
		Option "XkbVariant" ",,intl"
		Option "XkbOptions" "grp:lalt_lshift_toggle"
EndSection
Section "InputClass"
        Identifier "evdev internal keyboard"
        MatchIsKeyboard "on"
        MatchDevicePath "/dev/input/event*"
	MatchProduct "AT Translated Set 2 keyboard"
        Driver "evdev"
        Option "XkbLayout" "us,us"
		Option "XkbVariant" ",intl"
		Option "XkbOptions" "grp:lalt_lshift_toggle"
EndSection

Shouldn't it be possible to set the mapping in an evdev confg file in /etc/X11/xorg directory? If possible I think this is more natural than using an udev rule for this. Unfortunately I do not know how to achieve it.

I don't have a xorg folder in /etc/X11/ (ubuntu 21.04) should I create that?

Sorry, the correct directory is /etc/X11/xorg.conf.d/, at least in ArchLinux

If you don't have neither directory, maybe you can try searching where the .conf files are in /etc/X11, I suppose there should be some .conf files in there.

Hi, I'd like to make the space key of the second keyboard output hyper or some other key. Does somebody know how do do that?
