Comment 75 for bug 1386005

Ubuntu 16.04 newest nVidia drivers version 367.35. Same problem as everyone in here. Unable to enter password after installing the nVidia driver. Screen stays frozen with no input.

Well, what's worked for me as a workaround is to change: GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” in the /etc/default/grub to GRUB_CMDLINE_LINUX_DEFAULT=”” and then run sudo grub-update. It gives me the old style scrolling text login where I have an option to enter my filesystem decryption password. – ksclarke

I did that and it works but it is now the old plain login text you get from a distro without an user interface. Really ugly and not user friendly.
