That you don't get a graphical interface is another issue. I've read somewhere that if you attach a second external monitor it would work. Have you tried recovery-mode from GRUB-menu?
Also w/o more details what flavour of Ubuntu this regards and details on HW (at least graphics card) involved no-one can help.
