I'd like to use Xubuntu in 11.10 instead of Unity, how do I install it and switch to it?

If you want to also get rid of any "ubuntu gnomish" cruft, try psychocat's Pure XFCE – gregnotcraig Oct 4 '11 at 16:25

Instructions for 11.10 and 12.04

Install the xubuntu-desktop package - to do that, run the following:

sudo apt-get update && sudo apt-get install xubuntu-desktop

At some point during the install, you will be asked to choose between gdm and lightdm - I prefer lightdm, so thats what the screenshot shows.

Logout, you will be confronted by the LightDM manager.

Then, click the little cog wheel, and select Xubuntu Session.

Then, enter your password, hit Enter and you'll be logged into Xubuntu.

What is the difference between lightdm and gdm? – Alvar Oct 17 '11 at 8:09
@Alvar lightdm is installed by default, and (in my opinion) is prettier than gdm - lightdm is also easier on ram, CPU etc than gdm – James Oct 17 '11 at 10:14
What's the difference between Xfce session and Xubuntu session? I thought Xubuntu was Ubuntu using Xfce! – Alex Oct 20 '11 at 11:59
@Poldie XFCE is plain XFCE, Xubuntu is XFCE, but with some added tweaks to the config to make it "Xubuntu'ed". – James Oct 20 '11 at 12:00
Ok I'll start using Xubuntu Session tonight - thanks! – Alex Oct 20 '11 at 12:27

or use tasksel

sudo apt-get install tasksel
sudo tasksel

Check xubuntu and uncheck ubuntu.

And to remove original gnome desktop (after jrg's how-to) remove the package ubuntu-desktop

sudo apt-get remove ubuntu-desktop

You also sould do apt-get autoremove after doing that:

sudo apt-get autoremove

Removing gnome desktop isn't a good idea, it removes a lot of stuff that xubuntu-desktop needs as well. – James Oct 4 '11 at 15:00
Sure? I didn't read something like this. – fnkr Oct 6 '11 at 11:33
@jrg If xubuntu-desktop needs it, it should be listed as a dependency and won't get autoremoved. – graywh Apr 27 '12 at 16:05
