I am using GUI emacs 28.1 on ubuntu 22.04. Emacs won't let me reset the key C-;
I want to use:
(global-set-key (kbd "C-;") 'evil-normal-state)
Resetting the key C-. won't work either. The key C-; or C-. make a little popup with the letter "e" appear (see image below). It started to happen out of the blue, and I have no idea what it is.
Does anyone know how to stop that "e" to appear and reset C-; and C-. in emacs?
Once you disable C-; and C-. in GNOME Desktop, those keys will become available for Emacs to use.
GNOME to permanently disable C-; and C-. in ibus-setup$ ibus-setup
gsettings (preferably in a M-x eshell buffer) to narrow down the GNOME component of interest~$ gsettings list-recursively | grep '<Control>'

It took me a day to discover that that these bindings were set by ibus.
There were multiple instances where I ran in to the same issue ...

Elisp code to pry keybindings out of GNOME SettingsI am not a gsettings expert. Nevertheless, the below Emacs Lisp code will take you very far ... If something is amiss, you can fix the below code and pass it on to others.
