I've got the x1 carbon 6th generation with ubuntu on it and it's great. I don't have a docking station, I just have a usb-c monitor w/ usb and audio ports on it. I have to connect two usb-c cables when I get home (power and monitor). Supposedly you can buy usb-c monitors that also do power over the one cable but I guess I didn't get the right one.

I'll probably eventually buy https://www.caldigit.com/ts3-plus/ to get it all in one cable.
