For anyone struggling to find the basic commands to change the start up on your Ubuntu box to go to Desktop and not Terminal. Here it is...

sudo apt-get install ubuntu-desktop
sudo apt-get install gdm
sudo /etc/init.d/gdm start
sudo dpkg-reconfigure xserver-xorg

Will take a while to install but worked for me a treat on Feisty Fawn 7.04
