Ly, a lightweight tui display manager is available in 21.05 stable but I’m not sure how to use it. There is no config like lightdm or greetd that it seems to provide, nor do I find any documentation after searching. Any help is appreciated.

@matthewcroughan can probably help with that
I have a module for it here that is half-complete.
Put simply, ly doesn’t really work.
You won’t find that it sources .profile or .xprofile correctly. It also doesn’t launch sessions/seats properly. It requires a complete rewrite. It is not software that functions correctly.
See the numerous issues here Issues · fairyglade/ly · GitHub
I was hoping to get ly working since tuigreet (greetd) also has issues with xsessions. But, I wasn’t aware about the same issues with ly. Thanks for the info.
Something new on Ly?

I’m also waiting on more information about this… Been watching for months!
Setting up Ly in NixOS is on my TODO list, but after more important things like fixing my cars and getting my resume out for job interviews and cooking food… Agh but I would work on NixOS all day every day if I could!
I’ll post back here when I find the time to fully investigate. Ly is the slickest looking TUI login out-of-the-box and that’s all I care about for a login manager!

Looks like there’s a module in the works! Seems to be pretty much done?

## Description of changes
<!--
For package updates please link to a changelo… g or describe changes, this helps your fellow maintainers discover breaking updates.
For new packages please briefly describe the package or provide a link to its homepage.
-->
Tow notes:
1. I updated ly to the unstable one due to the fixes of config reading.
2. I made a wrapper for all ly necessary files which is linked into `/run/current-system/sw/` due to the line length restriction of configator used by ly.
### Test method
#### NixOS Test
`nix-build -A nixosTests.ly <your nixpkgs repo on this pr>`
This is successed.
#### NixOS VM
An example flake is here:
```nix
{
inputs = {
nixpkgs.url = "github:Vonfry/nixpkgs/init-ly-module";
};
outputs = { self, nixpkgs }:
let
system = "x86_64-linux";
pkgs = import nixpkgs { localSystem = system; };
flakeSpecialConfig = { pkgs, ... }: {
nix = {
package = pkgs.nixFlakes;
registry = {
sys.flake = nixpkgs;
nixpkgs.flake = nixpkgs;
nixos.flake = nixpkgs;
};
channel.enable = false;
nixPath = [ "nixos-config=${./.}" "nixpkgs=${nixpkgs}" ];
extraOptions = ''
flake-registry = /etc/nix/registry.json
experimental-features = nix-command flakes
'';
};
};
nixosConfig = { ... }: {
nixpkgs.hostPlatform = "x86_64-linux";
users.users.alice = {
isNormalUser = true;
description = "Alice Foobar";
password = "foobar";
uid = 1000;
extraGroups = [ "wheel" ];
};
i18n.defaultLocale = "en_US.UTF-8";
time.timeZone = "Asia/Shanghai";
console.keyMap = "dvorak-programmer";
virtualisation.vmVariant.virtualisation.cores = 8;
virtualisation.vmVariant.virtualisation.memorySize = 8192;
services.xserver.enable = true;
services.xserver.displayManager.ly.enable = true;
services.xserver.displayManager.ly.settings = {
load = false;
save = false;
};
services.xserver.displayManager.defaultSession = "none+icewm";
services.xserver.windowManager.icewm.enable = true;
environment.systemPackages = with pkgs; [ vim ];
};
nixosOutputs = {
nixosConfigurations.nixos-desktop = nixpkgs.lib.nixosSystem {
modules = [
flakeSpecialConfig
nixosConfig
];
};
};
in nixosOutputs // {
devShells."${system}".default = pkgs.mkShell {
packages = [ ];
SHARED_DIR = "/tmp/shared";
NIX_DISK_IMAGE = "/tmp/nixos.qcow2";
};
};
}
```
