I am using Ubuntu 12.04 from last week. This model of Samsung has Fn key, when used with F1 - F8, it can control brightness, volume and some other stuff.

Everything was working perfectly. Few minutes ago, I locked computer by Ctrl + Alt + L and started cleaning up the keyboard. When I logged back in, the F1 - F8 keys are working for controlling laptop features and they won't work for what they actually are.. i.e. Alt + F4 doesn't work anymore. Alt + Ctrl + F1 to switch to tty1 doesn't work.

It seems like, the Fn key is recorded as 'pressed' in the system. How do I resolve this?

While cleaning the keyboard, you would have pressed Fn Lock button which is next to the F12 button so the function keys are locked, press it again; it will unlock the function keys so that you can use the function key properly.
