Lightdm is quite faster than gdm so I'll use it. A brief log of operation required to use it. (installa package gnome-shell first)

sudo -s

#install a greeter, the login screen. unity-greeter seems buggy with gnome.
apt-get install lightdm-gtk-greeter

#set the greeter
nano /etc/lightdm/lightdm.conf

[SeatDefaults]
greeter-session=lightdm-gtk-greeter
user-session=gnome-shell
autologin-user=
 

#set gnome-shell as default
sudo /usr/lib/lightdm/lightdm-set-defaults -s gnome-shell

After a fresh ubuntu install, I was missing the network drivers. So, copyied the install iso content on an usb, proceed adding reference to sources.list

nano /etc/apt/sources.list

## add local dir to lists, should contain a dists/ folder
deb file:///media/disk lucid main restricted

#refresh the packages list
apt-get update

apt-get install gcc

make install
