A couple of days ago I got my new XPS Developer edition and I am really happy with it. It comes by default with Ubuntu 16.04.
The only issue, that is really small, is that super(win) key does not work for the Unity shortcuts and I don't know why.
I already try to change the shortcuts keys and reset it without any luck. I use the keyboard layout chart to confirm that I was pressing super key ( super key L is pressed, I don't know if this should be the issue ).
Any recommendation would be really appreaciate it.
