[LightDM] introduction and launching lightdm

[Catonano]

Hello

I'd like to try to write a system service for GuixSD for lightdm

Currently Guix is using SLIM

I'm not an expert, I don't now what I'm doing and yet I'd like to try anyway

The step no. 0 for me is being able to launch Lightdm manually

I prepared a virtual machine that has a bunch of services for running a
desktop

I copied them from the Gnome session that is currently being used by SLIM

screen-locker, udisks, upower, polkit, geoclue,  dbus, colord and some more

In such virtual machine I attempted to launch Lightdm manually but I failed

Nothing happened

How am I supposed to launch it ? With which command line ?

Thanks in advance
