I have 12.04 Ubuntu Studio Installed at the moment.

On removing a application called Terminal Emulator, I accidentally removed xfce too. As I am not very fond of xfce, I am OK with it as I can change the session to gnome 3 upon login. But session runs with occasional glitches.

My question is how to remove xfce completely and turn it into pure gnome system. I am aware of the way to do

apt-get install ubuntu-desktop

But, this is going to change the ubuntu studio, I dont want that. I just want to change my ubuntu studio to pure gnome without uninstalling ubuntu-desktop.

i.e. Something like ubuntustudio-12.04-gnome build. I've looked at this Q&A:

How to remove xubuntu?

The accepted answer removes some vital software from Ubuntu Studio such as Gimp, including ubuntustudio-desktop at the end.

ubuntustudio-desktop is a metapackage, which means it's not actually the packages that make the computer work, it just gets those packages in one bundle. sudo apt-get install lightdm will install the lightdm desktop manager, and sudo apt-get install gnome-shell will ensure that you have everything you need to run gnome. Synaptic package manager as said above makes it easier to find the packages for things like xfce4 than Ubuntu Software Center. Keep in mind though that in a beta release like 12.04 you will probably have "glitches" as part of life. Even in stable releases they occur.

But why uninstalling application like thunar ask for ubuntustudio-desktop to be uninstalled – Starx Apr 10 '12 at 11:35
Because ubuntustudio-desktop is a meta package. It's job is to allow you to install all relevant packages at the same time. Removing it does not remove the packages it depends on, because they do not depend on it. – Jo-Erlend Schinstad Apr 10 '12 at 14:55

Surely opening a Terminal within GNOME and typing sudo apt-get remove xfce would suffice.

no nothing... says unable to locate package xfce – Starx Apr 10 '12 at 10:51
how about xfce4, or whatever the model number of xfce you have is. Then hit sudo apt-get autoremove to remove dependencies no longer needed. If these don't work I would advise removing manually (with synaptic) all the programs you don't use – Joseph Apr 10 '12 at 10:53
I tried to remove a thunar, which comes with xfce, but it threatened me, that it will also remove ubuntustudio-desktop – Starx Apr 10 '12 at 10:56
it says xfce4, is not installed – Starx Apr 10 '12 at 10:58
ubuntustudio-desktop is a metapackage, – Joseph Oct 24 '12 at 14:13
