I have a UK keyboard and this is setup and functioning on Ubuntu 21.04 with all of my apps. When I open emacs inside a terminal using emacs -nw it also correctly used the gb keyboard layout. However when opening emacs (27.2, built from repo) in a new frame from a call to emacs or clicking on the shortcut, it switches to a us keyboard layout. I am unable to get it to use a qwerty-gb layout.

I have tried setting in my config/calling interactively:

(setq quail-keyboard-layout 'pc105-uk)

However whatever I choose doesn't appear to have any impact.

I have also tried interactively calling set-input-method british. This has had some help in the shift+3 is now '£' instead of '#'. However other keys such as my '#' come out as '\'.

Please could I have some help?
