Bug Description
Since I have upgraded to Ubuntu 17.10 Alt+PrintScreen doesn't work on my computer. I'm using Unity DE, with default settings.
The problem is not about taking screnshots.
xev recognizes when I press down the alt key, but nothing happens when I press Print Screen with alt being pressed (it does when PrintScreen is pressed by itself)
Here is evtest output when I press Alt+Printscreen:
# Alt pressed down:

Not sure how any of this helps, I would require somebody with graphics/keyboard stack to understand what/where has regressed.
