I have an older X1 yoga. I haven't tried to make the fingerprint sensor work, but the rest works quite well. Especially after I updated the firmware with fwupd. It's not my first Thinkpad running Linux, and the prior two ran quite well.

Imagine Microsoft or Apple telling their users that they have to live without a soundcard for 6 months during COVID-19 because "tough luck". Well that's pretty much how Canonical and Lenovo treat their customers.
