** Attachment added: "WifiSyslog.txt"
   https://bugs.launchpad.net/bugs/1575651/+attachment/4651971/+files/WifiSyslog.txt

** Changed in: linux (Ubuntu)
       Status: Incomplete => Confirmed

** 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).
+ 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)
