So I just updated to 16.10 (just got 16.04 a few weeks ago, still new to Linux). The keyboard still works when I need to enter my password to unencrypt the lvm drive, but stops working (along with the mouse) when I get to the login screen. Is this a known problem? How do I fix this? By the way this is installed on a lenovo think pad.
Edit: got home and tried connecting a usb keyboard. Does not work (again only after reaching the login screen) . What on earth is going on?
