I have a laptop which I use an external keyboard with. When I type using the external keyboard I want to use a US keyboard layout, since that’s the type of external keyboard I have. On the other hand, when I type using the integrated keyboard I’d like to use a Swedish layout.
Is this possible? And how would I go about doing it?
I’m asking here as I think we’ll find most Linux expertise here.
First, you have to find the device ID of the keyboard to change:
$ xinput -list | grep -i key ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Power Button id=7 [slave keyboard (3)] ↳ LITEON Technology USB Keyboard id=9 [slave keyboard (3)] ↳ LITEON Technology USB Keyboard id=10 [slave keyboard (3)]
Then change the layout using setxkbmap:
$ setxkbmap -device 9 dvorak
Some versions of setxkbmap need a ‘-layout’ argument:
$ setxkbmap -device 9 -layout dvorak
I can positively say that what you want to do is indeed possible. I achieved the specified scenario by first
sudo cat /dev/input/event(0,1,2..)
while typing on each keyboard to ensure that they were recognized as separate devices. Then I simply applied trial-and-error, experimenting with
setxkbmap -device (1-x) us.
I discovered that
setxkbmap -device 1 us configured both (all) keyboards, while
setxkbmap -device 6 us only affected the secondary. Of relevance is perhaps that they both were connected via PS/2.
This of course is not guaranteed to work for you, and doesn’t even classify as a proper answer, but it confirms that it’s at all possible. I don’t know according to which scheme the individual keyboards are named in
/dev/input, but I’m sure that the names can be specified in udev, making it possible to put the appropriate
setxkbmap command in
/etc/rc.local or similar.
Although this question is a tad old, I’d thought I’d share my solution since none of the other answers addressed how to have this work on boot.
I have a Happy Hacking Keyboard that plugs in via usb that has keys moved around (control where caps lock is, etc). I use this most of the time, but sometimes I would like to use the standard laptop keyboard or another usb keyboard. For these keyboards I created a custom keyboard layout.
The trick is that the custom keyboard layout should not be applied to the Happy Hacking Keyboard.
I created a Xorg config file as such:
$ cat /etc/X11/xorg.conf.d/30-keyboard.conf Section "InputClass" Identifier "Happily Hacked Keyboard" MatchDevicePath "/dev/input/event*" MatchIsKeyboard "on" Driver "evdev" Option "XkbLayout" "us" Option "XkbVariant" "hhk" EndSection Section "InputClass" Identifier "Happy Hacking Keyboard" MatchIsKeyboard "on" MatchVendor "Topre_Corporation" Driver "evdev" Option "XkbLayout" "us" Option "XkbVariant" "basic" EndSection
The first part basically says for any standard keyboard, apply the us layout with the the custom variant. The second part says for the happy hacking keyboard, use the us layout with the basic variant.
You can match devices based on a bunch of parameters: xorg doc
It might be possible, judging by the -device argument to setxkbmap:
-device device Specifies the numeric device id of the input device to be updated with the new keyboard layout. If not specified, the core keyboard device of the X server is updated.
Naturally, however, I do not have a second keyboard to try it at the moment.
