SUMMARY My setup is notebook (closed lid, screen disabled) + docking station + 2 external monitors. Sometimes after suspending notebook when I return to it, I only see black screen and mouse cursor. There is not way to unlock the session. I've seen several hints, but none of them works. I tried blindly typing password and pressing enter. I tried switching do tty2 and back to tty1. What I didn't try yet is 'loginctl unlock-sessions' in different tty. Will report on that later. Only thing I can do is either reset my notebook or kill X with Ctrl+Alt+Backspace. STEPS TO REPRODUCE This is random bahaviour, so can't reproduce it every time. Sometimes I see this behaviour also when I disconnect notebook from docking station and then open the lid.
