I use a 6th gen X1 Yoga at home (for its oled panel and integrated wacom tablet) and an 8th gen X1 (non-yoga) at work. (note - the generation I refer to is the processor generation, ie the 6th gen is an i7-6600u, which lenovo calls a first gen x1 yoga)

The yoga needed some tweaks to get the OLED brightness to work correctly, but other than that they basically worked out of the box under ubuntu 18.04. My only complaints are that the oled panel only came in gloss and has since been discontinued (although there are rumors that a 15" 4k oled will be available on the x1 extreme), and that the mouse click on the yoga is several orders of magnitude too loud. The trackpoint buttons are fine and the keyboard is great, but the trackpad click is loud enough to hear in the next room over.
