How to install kde-plasma with lightdm instead of kdm

Question

I like lightdm and especially its webkit-greeter a lot. Is there a way to install kde without installing kdm and using lightdm instead?

I have tried everything from installing kdm and then remove it to dpkg-reconfigure kdm and lightdm to lightdm is the default. but I always got kdm when I boot up or a broken system, when I remove it completely.

Does anyone know how to get kde together with lightdm?

By the way. I am doing this on a minimal installation.

Solution

Since your initial setup is a minimal installation, I'll take Ubuntu 14.04.1 Server as the base OS.

After installation, all that you get is a command-line prompt without lightdm nor a desktop environment.

Open a user session and type the following commands:

sudo apt-get update
sudo apt-get install lightdm-webkit-greeter --no-install-recommends
sudo apt-get install lightdm --no-install-recommends
sudo apt-get install kubuntu-desktop --no-install-recommends
sudo reboot

Now the lightdm greeter will open a kde plasma desktop:

@Fabby Merci, but continue to propose great answers! I think we're all looking for questions where the problem solving part 1. is fun and 2. can teach us new stuff about Ubuntu.
