I want to install KDE in my Ubuntu 12.04 .

I am using LightDM. So how can I fully install KDE? I do not want to remove LightDM.

I want KDE but without any confliction with it.

Display managers

There can be multiple display managers installed. You can then pick/change the default dm by running the dpkg-reconfigure.

man dpkg-reconfigure

NAME
       dpkg-reconfigure - reconfigure an already installed package

SYNOPSIS
        dpkg-reconfigure [options] packages

DESCRIPTION
       dpkg-reconfigure reconfigures packages after they have already been installed. Pass it the names of a
       package or packages to reconfigure. It will ask configuration questions, much like when the package
       was first installed.

       If you just want to see the current configuration of a package, see debconf-show(1) instead.

Changing dm (kdm/gdm/lightdm)

sudo dpkg-reconfigure kdm
