Keyboard cuts off intermittently (sometimes mouse as well) Ubuntu 18.04.1 LTS?

Question

ubuntu

Good day, such a problem is on the machine Ubuntu 18.04.1 LTS. From time to time, the keyboard simply stops responding somehow (diodes of the num lock caps, etc. go out and do not respond) (I don’t pull the wires, the system manager doesn’t fuck), at the moment the problem is solved as follows: 1) Get the connector 2) Insert the connector . Google doesn't help. I would be very grateful if you advise something (or maybe someone had such a problem).
Thank you!

Answer 1

Are you sure the problem is with Ubuntu? This also happens when the motherboard gets out.
