mod-dh VS tuigreet

I have made this, I guess it's what you need?

xorg uses a different keymap format than console, but you should be able to use one of these in /usr/share/kbd/keymaps like you said

My DH version is this one: https://github.com/ColemakMods/mod-dh/blob/master/autohotkey/colemak_dh_ansi.ahk

Github mod-dh

I'm using a script to convert my Keyboard to the Colemak-DH-layout. More specifically, it's this script.

Understand how to write an xmodmap file. See example in https://github.com/ColemakMods/mod-dh/blob/master/xmodmap/colemak_dh_ansi_us_wide.xmodmap

Any reason you can't use this version https://github.com/ColemakMods/mod-dh/tree/master/macOS

Check out https://github.com/apognu/tuigreet if you want a terminal based display manager.

Many PRs have been opened to add Ly to the repos, they've all been rejected because of the submodule thing and because it's had some severe technical issues. I really don't understand this subreddit's obsession with that specific greeter. If you want something in the repos that provides an almost identical interface, use greetd + tuigreet.

i like greetd using tuigreet

Relevant Github issue.

However, from what I understand, I think that setxkbmap only sets the layout after starting Xorg. Infact when I first boot the computer and get to my display manager tuigreet (which is a TUI application that runsi in a tty), I have to type my credentials in QWERTY because of course Xorg has not started yet.

I like it because it just works. Install the packages, set greetd to use tuigreet, enable the greetd service, and you're done. Also subjectively I like the UI better.

Knowing the alternative tuigreet (https://github.com/apognu/tuigreet), there won't be much of a difference between a video and the given screenshot. You have a prompt, you enter username and password and your Wayland compositor/X session starts up.
