The monitors does not seem to blink black in linux-4.1.3 for me.  @noga.dany:
can you please confirm if its the same for you too?  

The monitors, however, stay blank after resume.  Switching back to a virtual
console seems to work sporadically now.

Is there any way in which I can help debugging for this bug?
