I've had a couple of X1s and T series throughout the years, and ran Ubuntu and Arch wonderfully. Save for the fingerprint sensor (where I think the issue is not drivers but rather that fingerprints don't have enough entropy for a keyring), they actually ran way better than my current Windows X1 which BSODs every 3 days.

I think the yoga subbrand is a lower end model, so maybe they're sloppier there?
