Ooops, sorry, this is apparently not about the keyboard but the notebook
screen. Though, adjusting screen brightness works fine on my new XPS 13

I can confirm this is obviously *fixed* in Ubuntu 14.04.3 LTS running on
XPS 13 Developer Edition notebooks bought in August 2015. The keyboard
backlit can be adjusted using the Fn+F10 (oder just the F10 key when the
Fn-lock is on, like I have it).
