[Bug 1732612] Re: Alt+Printscreen not working (doesn't generate keypress event)

[Rüdiger Kupper]

Same problem here, and workaround in #10 NOT working.
I confirm the OP's analysis: ALT+PrintScreen does not generate a keyboard event. Other Keystrokes (ALT alone, PrintScreen alone) do.

Title:
  Alt+Printscreen not working (doesn't generate keypress event)

Status in systemd package in Ubuntu:
  Confirmed
Status in unity package in Ubuntu:
  Confirmed

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:
