I updated from a screenless Wacom to an XP-Pen screen tablet. The tablet hardware itself is good (but also I moved up several product categories) for less money than the Wacom, but the experience getting it to work on Linux was reminiscent of trying to get wifi to work 15 years ago. I got there in the end, but it was not smooth.

I use an Xppen 24" Pro display tablet. I enjoy using it but my Linux mint machine simply won't boot with it plugged in. I haven't figured out a workaround beyond physically disconnecting both cables every time. And when I boot up and reconnect, my machine never remembers the screen mapping, so there's enough friction there for me to avoid plugging it in for days if not weeks at a time.
