Public bug reported:

To reproduce, remove the X220 from the dock. The brightness is set to
minimum (the screen is nearly unreadable) and the brightness control  is
broken, you can't adjust it by hardware keys.

The symptom is fixed by docking and undocking again.

This is the same problem as discussed
