Can't install gnome-session on lubuntu 12.04

Question

I did a clean install of Lubuntu 12.04 and I want to install the gnome3-session

I tried

sudo apt-get install gnome-session

Then I logged out. When I login on to the gnome-session I’m still getting the unity-layout.

Have I done something wrong? If so what do I need to do to fix it?

Answer 1

I replaced Unity with Gnome in the following steps

1. Install Gnome

   sudo apt-get install gnome-shell 
   

2. To set gnome-shell as default, open a terminal and type

   sudo /usr/lib/lightdm/lightdm-set-defaults -s gnome-shell  
   

3. And to remove unity after installing gnome-shell

   sudo apt-get remove unity unity-2d unity-2d-panel unity-2d-shell
