While in DRM backend, all weston_keyboards seem to use the global keymap. It can be changed by setting up `weston_compositor_set_xkb_rules` before `weston_compositor_wake`. After that, there is nothing I can do. It is used to be possible to call `weston_seat_update_keymap`, but It is now an internal API. Even by that I think it would be a nasty way to change keymap.<br>

> Sorry for the language, yesterday when I was quite confused when I was reading the keyboard handling in weston. If I am getting this right, In the beginning keyboard is using global xkb_info, but once we called `weston_seat_update_keymap`. Keyboards will create their own xkb_info. Leaves the global xkb_info useless. I guess that is why `weston_seat_update_keymap` was never called directly from a compositor.<br>
<br>
No problem. And yes, you're right - at the moment you'd be the only<br>
person changing the keymap at runtime. `weston_seat_update_keymap` is<br>
definitely something we could re-export, as that's the correct way to<br>
do it.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">Thanks for your reply, I just submitted a new MR for this, I found that the `compositor->xkb_info` is kind of redundant since most of backend is not using it and </div><div dir="auto">weston_compositor_building_global_keymap is creating new keymap anyway, so keyboards are not sharing global xkb_info.
