Saved a Lenovo 20TG from the dump a couple weeks ago. Wiped and installed Linux Mint, which works well for the most part. There's not much Linux support for the external eink display, but I did find a driver here: https://github.com/LizardKing00/thinkbook-eink
Now, this driver comes with a system monitor tool, but I wanted the orientation flipped around AND some furry art on there (what's the point of a display if it's not showing furry art, I ask you). Fortunately, the driver also comes with a tool to send over a static image to the display. Wrote a kludgy little python script to grab some system info using inxi, then write that to a template image (containing furry art, yay) rotate the image, and use the setbackside utility from the above driver to shoot the image over to the eink display.
It's not pretty right now, because I don't know how UIs work. It's also pretty slow, but I can still get about 10fps which is solid for an eink display!
