Hi tumashu!

The patch looks good. Does it work for you? It does not find any
input methods on my system, but perhaps I need to install some?

If you can confirm that this works for your use, I think it can be added
as it is, save for some minor changes to make `guix lint` happy. I will
add the same copyright header as the other patch if that is okay.

Thank you!
