Ubuntu 12.10
I recently allowed the current update that involved Kernel 3.5.0-27-generic and got the blank screen issue. I was not able to ctrl-alt f1 etc.
What I did do, was reboot and at the grub menu, chose Advanced Options and then selected the the "Ubuntu, with Linux 3.5.0-27-generic" and hit the right arrow, and it boots happily. However, as long as I simply hit enter on the "Ubuntu" menu it boots to black.
I don't see any difference between the two entries in grub.cfg so I can't understand what would be different from hitting enter when the grub menu comes up, versus going into the Advanced menu options and selecting the kernel.
Here is just a snippet of the grub.cfg for those two entries.
