Alternative window managers
From nUbuntu Wiki
FluxBox is the default window manager in nUbuntu and the only one available when using a Live CD. However if you have installed nUbuntu to your hard-drive it is possible to install any window manager you might want.

GNOME
Installing the GNOME Desktop
First, login and run 'startx'. This will start FluxBox.
Now, open a terminal and type:
'sudo apt-get install ubuntu-desktop'. (Alternative: sudo apt-get install gnome)
Follow the instructions.
NOTE: This will download and install all the default Ubuntu applications; games, accessories, office applications. Basically all the things removed by the nUbuntu team...
Now you have GNOME installed, but to use it you have to enter the command:
'sudo dpkg-reconfigure gdm'
and then reboot.
Now you will be shown a familiar login-window at startup, but in order to load GNOME you have to click 'Options', 'Change Session' and choose GNOME from the list.
Uninstalling the GNOME Desktop
To remove the GNOME Desktop, logout/startup to the GDM Login Screen. Press 'Session' and choose 'Failsafe Terminal'.
Here you will need to issue two commands, in order:
'sudo dpkg --configure -a'
'sudo apt-get autoremove ubuntu-desktop'
Then run 'startx' to start FluxBox (alternate command: 'fluxbox')
KDE
Installing the KDE Desktop
First, login and run 'startx'. This will start FluxBox.
Now, open a terminal and type:
'sudo apt-get install kubuntu-desktop'. (Alternative: sudo apt-get install kde)
Follow the instructions.
NOTE: This will download and install all the default Kubuntu applications; games, accessories, office applications.
Now you have KDE installed, but to use it you have to enter the command:
'sudo dpkg-reconfigure kdm'
and then reboot.
Now you will be shown a familiar login-window at startup, but in order to load KDE you have to click 'Options', 'Change Session' and choose KDE from the list.
Uninstalling the KDE Desktop
To remove the KDE Desktop, logout/startup to the KDM Login Screen. Press 'Session' and choose 'Failsafe Terminal'.
Here you will need to issue two commands, in order:
'sudo dpkg --configure -a'
'sudo apt-get autoremove kubuntu-desktop'
Then run 'startx' to start FluxBox (alternate command: 'fluxbox')
