No experience yet on power management, but even as a noob on Linux, and someone who didn't install an OS since Windows XP, I got Ubuntu running within 2 hours on my X1E Gen2 today. Pretty straight forward, and all functions work. I didn't try fingerprint scanner and dual GPUs. The first already was a nuisance under Windows and the latter deactivated from day one of ownership to get multiple displays properly running. Even Steam and most of my games are running just fine.
That being said, he nVidia GPU managed to suck the battery in 2-3 hours depending on the game being payed under Windows as well, everything around 4 hours on normal working is fine.
Installing software under Linux / Ubuntu is, well, strange. But solvable. And I really do like the old-school, non-cloud feeling of Linux way better than Windows 10 and One Drive.
