Public bug reported: Once my session has been locked and the screen off, Xserver stops responding to input ( I can still move the cursor). I can re-activate it by typing in a tty "xset dpms force on". If I just lock the screen all works fine. If I just turn off the monitor (xset dpms force off) all works fine.
The same system (kubuntu 16.04 64bit) on different hardware (nvidia) has no problem.
