According to this page I can have two different physical keyboards attached and have a different layout on each of them. I need German on one, and Danish on the other, so this would be a very elegant solution.
However, my xinput command output does not show me two keyboards; the wireless Logitech K230 keyboard is listed as a pointer because it uses the Logitech "Unifying Receiver" that also receives my wireless mouse. Also, the USB keyboard is shown as id 11 and 12?
$ xinput
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech K230 id=8 [slave pointer (2)]
⎜ ↳ Logitech M705 id=9 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Sleep Button id=7 [slave keyboard (3)]
↳ UVC Camera (046d:0991) id=10 [slave keyboard (3)]
↳ SINO WEALTH USB Keyboard id=11 [slave keyboard (3)]
↳ SINO WEALTH USB Keyboard id=12 [slave keyboard (3)]
I have discovered that I can use setxkbmap on device 3 to affect both keyboards at once.
setxkbmap -device 11 at also affects device 8 (the Logitech keyboard).
setxkbmap -device 8 dk works - but only until I type anything at all on the USB keyboard! From then on, both keyboards have the at layout.
- How do I assign different layouts to these two keyboards?
- Why does using one keyboard affect the other keyboard?
This unanswered question from 2017 says that "Apparently, the [Logitech keyboard] has no layout of [its] own... it just uses the layout of the last keyboard that has been used." Since nobody has answered there, perhaps that is really an unsolvable problem? Perhaps specific to Logitech?
