** Tags added: apport-collected

** 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.
  
  The issue does NOT occur when running this kernel:
  - linux-image-4.6.0-996-generic (4.6.0-996.201604262201)

Title:
  X stops responding to input on power saving mode

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  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).
  No errors in dmesg

  Frequency/conditions:
  Occurs almost every time the screen enters power saving + locked (possibly DPMS issue?)

  
  The issue does NOT occur when running this kernel:
  - linux-image-4.6.0-996-generic (4.6.0-996.201604262201)
