** Description changed: 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. - Symptoms: - After waking the screen from power saving/screensaver, the primary display wakes but X stops responding to input (the mouse cursor can still move, but clicking has no effect). Secondary display does not wake. - No errors in dmesg - - Frequency/conditions: - Occurs almost every time the screen enters power saving + locked (possibly DPMS issue?) - - VGA: Advanced Micro Devices, Inc.
