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.

They dock from the side. It works with Linux too except I have this annoying bug where my attached monitor turns off and back on randomly a few times per day.

You can get most of that through thunderbolt hubs these days, there's little need for proprietary docking station connectors.

PSA to everyone using a recent ThinkPad: Update your thunderbolt firmware. Boot into Windows if you have to... This one is a might-break-your-hardware class bug.

Damn. Thanks for the heads up. I erased windows without ever booting it, but hopefully this can be done without it.
