I had the exact opposite experience.
Perhaps it's a Unbuntu thing, hard to know, I use Fedora, or perhaps it's the Yoga...
In 2004 I got a T42, installed Fedora on it, it just worked.
In 2013 I got a T440p, installed Fedora, just worked. That Laptop is still in use, btw.
This year I got a X1 Extreme Gen2 (stupid name), installed the Fedora KDE spin, just works.
Sleep, etc, works, battery is life is really, the graphics card (internal and dedicated with the Nvidia drivers) work, etc, etc. So I am truly surprised by your experience.
I did a lot of research before, and these are the best Linux laptops that I could find (besides the "open" laptops like System76, etc).
The again, I am an engineer, so perhaps what I do in terms of setup comes easy to me without me noticing the complexity.
