I try to configure an ergodox-ez keyboard with developper layout but also to be able to type french text.
So I don’t want to set US-International layout because I don’t want dead key on all
` when I develop.
All can be done by command line but I prefer using gnome tweaks GUI.
It can be installed with ubuntu software or with
sudo apt install gnome-tweaks
On keyboard & mouse part setup a compose key.
Enable the compose key and choose your preferred key.
In y case
With Oryx you can add modifiers on a key.
You can do it for most useful french accents like
Now you can type your new dead key and the required letter and enjoy typing accents.
