Subject: bug#73859: [PATCH 0/2] lightdm: Fix empty session list.

From: Dariqq <[email-masked]>
Date: Sat, 2 Nov 2024 10:18:31 +0000

This changes lightdm and the service to use the config file from a well-known location in /etc/lightdm/lightdm.conf s.t. the gtk-greeter knows about our custom "sessions-directory".

I then removed the custom config file from the lightdm servcice and removed passing XDG_CONFIG_DIRS which are no longer neccesary.

Renamed lightdm-configuration->greeters-config-dir to just lightdm-configuration-directory (inspired by how the dbus-service names its directory) and also moved the etc-extension into a seperate procedure for consistency with other services.

I tested this on my i686 pc and ran 'make check-system TESTS=lightdm' successfully

This is also the approach done on NixOS, see

*https://github.com/NixOS/nixpkgs/blob/nixos-unstable/nixos/modules/services/x11/display-managers/lightdm.nix#L259

Fixes https://issues.guix.gnu.org/68055
