When I open the lid, the system recovers from sleep, the display shows the screensaver, but the keyboard does not react on any input. I'll have to wait several minutes, bevore the keyboard accepts input and I can log in again. Mouse works normal. What should happen: When I open the lid, the system should recover normally and the keyboard should accept input to let me log in.
