Instead of booting into your normal kernel, boot into the Recovery kernel. That should have an option to "Try to recover xserver".

Try that.

And once you have a working system you want to install the proprietary Nvidia drivers, the easiest way is to first install envyng plus the latest Nvidia drivers from the repositories and then run it.
EnvyNG will give you options for ATI and Nvidia, you might want to be conservative and not select the latest on first attempt.

Would you after reboot again end up with a black screen you can start up from the recovery mode and type into the command line "envyng -t", this will give you options to get back to a known and working driver.
