Topic: Linux and the keypad
There is a keypad, completely the worker. Further goes about indicator Numlock. It too the worker. Further, I load from a flash card ubuntu 16. While it is loaded, on numlock leads to appropriate fire-extinction of the indicator. system Numlock loadings the indicator more goes out also does not react to pushings. But, as it appeared, the operation mode reacts to pushings Numlock. Pushed Numlock - the dial-up of digits works, - pushed - the dial-up of digits ceased to work. But the bulb does not react. A question - as well as what for so it is made?
