I have a 4th gen X1 Carbon with Ubuntu and everything has worked fine. Even the functional buttons like screen brightness and volume work for me.
On the other hand, the palm detection does not work or is just terrible because I find myself constantly randomly tapping or moving the cursor when typing. Indeed it's moving around as I type this.
I ended up just disabling tap to click which I actually love using, but besides that it's great. I definitely long for the day when Linux touchpad support will match OS X's. Still, I really like the keyboard and the little nub thing is pretty awesome too, although I haven't really gotten used to using it.
