Like most computer keyboards, the X1 has secondary "buttons" assigned to each of its function keys, F1 through F12, that are accessed via the Fn modifier key. As example, Fn+F1 will toggle device audio, whereas Fn+F8 will toggle the wifi card. However, the X1's secondary buttons for the F11 and F12 keys do not work by default on X server.
Luckily there seems to be a fix already on the arch wiki here that I can add when I have the chance.
