Not much experience with Ubuntu, but I think that the command is dpkg-reconfigure xserver-xorg. This command will setup your x server and hopefully get you up and running. So, at the command line type, without the quotes, 'sudo dpkg-reconfigure xserver-xorg'. Enter the password, which should be the same as your users'. You can probably accept most of the defaults. When you are done type 'startx' and see if it worked, or reboot and see if it worked.
