I've installed Ubuntu 11.10, but I was not happy with Unity, so I switched to Gnome 3 (classic).

This was also not the best for me, so I've tried LXDE. Again was not exactly, what I'm looking for. So I've tried Xfce. Now i'm happy with this solution. I don't need Gnome, Unity and LXDE anymore. I've tried to remove ubuntu-desktop. It was possible, but all applications, which are installed with Ubuntu are still here.

How can I remove Ubuntu/Gnome/Unity/LXDE completly?

As you can see it is a long list, and likely could be simplified. You might wish to review the list and make sure there are no applications you wish to keep.

In addition, you may want to clean the configuration files in your home directory. (apt-get will not remove them).

If you are open to a few suggestions, if at all possible it is sometimes easier to run Ubuntu in a Virtual Machine, such as VirtualBox or KVM. You can try various packages or window managers and settle on a set you like.

You then install the appropriate version (l/x/k/ubuntu) on your hardware.

i will try to make the changes on my machine :) no risk no fun...the worst case - i must reinstall. –  cupakob Jan 25 '12 at 19:11

First of all, I need to warn you that Ubuntu comes pre-packaged with both Unity and Gnome, and many applications & features depend on them or their libraries. If you decide to follow any of the instructions below, you're doing it at your own risk. If you decide to remove those packages, it may be a good idea to run a simulation first. It will give you an idea of what will be removed. You can run simulation by adding the -s flag, eg:

sudo apt-get -s --purge remove package_name 

To get rid of Unity (Ubuntu's default session), you have to remove unity packages:

sudo apt-get --purge remove unity*

As you may notice, there is a --purge flag. Adding it will also remove all associated configuration files.

To remove Gnome, your best option would probably be this:

sudo apt-get --purge remove gnome-*

Once again, I need to stress that many popular applications depend on Gnome's libraries and may refuse to work or be uninstalled along with Gnome.

Finally, in order to remove LXDE, your would probably run:

sudo apt-get --purge remove lxde*

As for the remaining applications, they are probably independent from Unity and you will have to remove them manually.

The question is, how to find, which packages must be removed, so i get clean xubuntu installation. –  cupakob Jan 25 '12 at 19:08
