How to use a certain keyboard layout from emacs as Ubuntu keyboard layout

Question

Good day,

I would like to use a certain keyboard layout outside of emacs, namely french-keyboard yet unfortunately I am not able to locate the definition of the keyboard layout. My question is as following:

1. Where (which emacs file and where is it physically location) can I find the definition of xyz keyboard layout?
2. What would be the most comfortable way to (here the question would overlap with superuser forum) use this layout as a general Ubuntu layout?

Many thanks in advance

Answer 1

The input method you mention is defined at lisp/leim/quail/latin-post.el. You can take a look here.

As for your other question, you need to configure the input method on the level of your window system (Xorg or Wayland). Perhaps you can define a custom one, if not available. Or you could use EXWM and let Emacs manage the input method.
