I've got a Thinkpad L14 with Ryzen 7 Pro 4750U, 16GB, Radeon.
I had Mint 20 running on it briefly. Everything (that I tried) worked perfectly, except that the trackpad was jumpy. Eventually got fed up with the imprecision and put Win10 back on it (I still run Mint on a Yoga S730 and have Ubuntu under WSL2 on the L14).
I'm sure I'll try again at some point as it is probably a simple fix; I just couldn't spare the time to investigate. I'm assuming as this is a fairly new machine, when I try again in a few months it may work better.
