I'm using Lubuntu for a while now, but found a couple of details that I wanted to view with Unity (that's another story).

Ok, the thing is: I've tried on a VM with Lubuntu to install Unity (sudo apt-get install unity) When the installation is over. I selected in the Lubuntu login Unity/Unity2D but did not work.

Right now I'm installing ubuntu-desktop, I am presuming that will work, but also it will change my login for example.

Is there a way to do a "clean" installation of Unity but not make major changes on my Lubuntu?

I would prefer Gnome-Shell instead of Unity.

Unity is build on the top of gnome3 –  Tachyons Mar 6 '12 at 14:39

In essence, you have to accept the changes if you want to get a proper working Unity or Gnome Shell. They have dependencies. –  RolandiXor Mar 6 '12 at 14:53

To install unity, run the following command in a terminal:

sudo apt-get install ubuntu-desktop

To install gnome-shell, do the same in a terminal:

sudo apt-get install gnome-shell

You can choose the default login manager as per your preference.

Would there be a performance hit in doing so? –  Akmur Oct 22 '12 at 19:38
    
@Alex: it will not affect perfomence of default DE, but gnome-shell is slower than lxde(default de of lubuntu) –  Tachyons Oct 23 '12 at 2:36
    
How do you choose the login manager? I'm using Lubuntu to run a very old machine, but if I have to go much longer without the Unity panel, I'm going to explode. Other than the unity panel, I want all the other things to be the default lightweight Lubuntu things: the login screen, etc. Is the Unity panel incompatible with LXDE? –  JamesTheAwesomeDude Dec 15 '12 at 17:46
    
If you are using 12.04 , you can use unity 2D panel in lubuntu. Unity-3D panel is not compatable with lxde –  Tachyons Dec 16 '12 at 1:44
    
JamesTheAwesomeDude: Just check this screencast about add a second panel like unity panel but on lubuntu: blip.tv/ubuntu-switcher/… –  Celso Dec 18 '12 at 0:35

It is very easy to install Gnome-shell in Lubuntu 12.10.

Open Synaptic Package Manager, reload it, search for Gnome-shell and install it. There is no need to install Ubuntu-desktop.

You can also agree to install GDM, which would give you a nice log in screen.

Restart and log into Gnome.

I am writing from Lubuntu + Gnome shell. No crashes.
