I'm having some trouble with my shortcuts on Kubuntu 15.10 with usb keyboard.

Distribution

Codename:       wily

Setup

Show desktop grid

Meta+x

Present windows

Behaviors

• Laptop keyboard

  • Meta+X: show the grid as expected;
  • Meta+A: present windows from current desktop, not as configured (should be windows from all desktops) ;
  • Meta+Q: present windows from all desktop, not as configured (should be only current desktop) ;

• USB TypeMatrix keyboard** ;

Answer 1

The order in which you specify your layout is relevant. Based on section (french) TypeMatrix#Trucs et astuces section or TypeMatrix USB-2030-B you can try to emulate a 106 keys keyboard.
