These instructions are for installing the Xubuntu Core Desktop in Ubuntu 12.04 running the Unity Desktop.
Installation instructions may be the same or similar for other versions of Ubuntu or for other Linux distros, but no guarantee is made.
Installing Xubuntu Core Desktop installs only the GUI part of Xubuntu Desktop without all the extra applications that are part of the Xubuntu Desktop package (the only extra application it installs is the Thunar file manager)
The Xubuntu Desktop is a custom configured version of the Xfce Desktop.
Xfce is smaller than Xubuntu Core Desktop. Installation instructions can be found here.
An article listing alternative desktops for Ubuntu 12.04 can be found here.
If you are changing desktops because you are totally lost / confused by Unity, I suggest reading this tutorial and giving Unity a chance.
Of course, if you really hate Unity, then Xubuntu Desktop is an alternative desktop.
Xubuntu Core Desktop will install 111 MB of files and data to your hard disk.
Some images may be clicked for full sized versions.
What it Looks Like
The basic, straight-out-of-the-box, look of the desktop is:
Compared to the Xubuntu Desktop, there are some minor differences.
Installing From the Command Line
If you are comfortable with Linux and know how to use the command line and apt-get
then the command is:
sudo apt-get install xfce4 xubuntu-artwork xubuntu-default-settings
Detailed instructions for accessing a command line can be found here.
Afterwards, restart your system. It should be enough to just log out and the log back in with the new desktop, but it doesn’t hurt to restart.
Installing From the Ubuntu Software Center

Selecting the Desktop
After the system has restarted, it is necessary to select the new desktop from the login screen.
It is only necessary to select the desktop the first time after installation. Ubuntu will remember your your desktop for future logins.
You can even install multiple desktops and switch between them.
14) Click the icon in the top right of the Login box:
15) Select Xubuntu Session:
Xubuntu is a customized version of Xfce. This is why an Xfce session appears as well.
If you select Xfce Session then you will get the standard Xfce desktop.
16) Login:
Notice the icon in the upper right hand corner has changed to a different icon. Some, not all, desktop environments will present an icon there.
If an icon is present, this provides a quick way to see which desktop environment you are logging into.
