Even a total Linux noob like myself (never touched it in my life) that installed his last OS like over a decade ago got Ubuntu on a X1E Gen 2 in around 30 minutes. No issues, Windows stays for the odd things that don't work under Linux (some Steam games, mostly...).

I'm running linux for a while now (20y+). I got it to work well on the Yoga7 Slim, but it required some tweaking (which I dont mind).

X and T lines seem to do better with linux out of the box.
