The login screen comes up but one cannot login because both the keyboard and the mouse are USB attached devices, and are not working. I was able to login and use the computer by using the advanced mode in Grub and then reverting to kernel 3.13.0-45 generic. I could also login if I used the advanced mode and then loged in to the recovery mode of kernel 3.13.0-51 and just selected the resume entry in the offered menu.
