Just a few days ago I installed Arch Linux on a ThinkPad P15 Gen 1 with X Server and i3wm for wm, disk encryption, multiple displays and it works very well. Heck, even the touch screen is working OOB without any special configuration. I've always been installing Arch Linux on ThinkPads that came with Windows pre installed. There are minor issues at times with backlight control or sound system which is mostly due to my minimal setup but overall I don't feel that ThinkPads don't play well with Linux.
Running NixOS unstable on a ThinkPad X1 Carbon 7th gen. Sway tiling wm, Wayland, fractional scaling, damn long battery life, hardware acceleration on Firefox, fingerprint reader all work 100%.
I'm surprised how good this is, and I've been using ThinkPads for a long time. This model works way better even compared to the mighty X230 I still love and adore as a great product from the past.
