Try letting the live cd run until you hear the Ubuntu welcome screen sound from your speakers, then ctrl+alt+backspace, this will reload x-server and hopefully give you a screen you can see. This worked for me.
So THAT'S what happens if you press ctrl+alt+backspace Guru, just tell me does it tells you anything ?? :?? Hahaha, I just have to remind you if you don't remember It was great... it was in Linux Ubuntu, yeah *ROFL*
