Keyboard not responding at login with 12.04 dual boot on toshiba satellite L775

Question

Just created a separate partition to load Ubuntu 12.04 as a dual boot on a Toshiba Satellite L775. OS installed perfectly and is running flawlessly. The keyboard is not responding at login screen randomly. The virtual keyboard works and the mouse works but the keyboard is unresponsive. After rebooting a couple of times it is responsive again and works with no issues. Went in to keyboard shortcuts and disabled a few of the superfluous media short cut keys in the off chance that it is hinging on a rogue key command that this series of laptop uses. Is there a command line that will debug this issue? Thanks
