Bug Description

Simply put, using Ubuntu 14.04, the keyboard can't be used to enter the password at the lightdm login screen after booting. You can use the mouse to click on items and even use the keyboard to switch to a different tty session, but you cannot type in the password bar until ~30 seconds later.
