I just upgraded to 16.04 and can't log in any longer with the latest (default) kernel 4.4.0-21. If i select an older kernel (4.2.0-35) everything works fine. Trying to load nvidia drivers manually say something like 'required key missing' (i would have to reboot with the latest kernel to see the exact wording however).
