I'm trying to get this (XP-PEN Star 06) tablet to work. I tried DiGiMend on github and installing their drivers etc... did not work. Here is my complete output for the tablet. https://pastebin.ubuntu.com/p/d5DFQ8V3ZG/
I just ordered this tablet and am waiting for it arrive but looking around for linux drivers I found that Xp Pen have actually released a linux driver Checkout this page https://www.xp-pen.com/download/index/cid/36.html
XP-Pen tablets do not work on Linux full stop. Be a hero and write a driver for it; or else weigh the value of your time spent doing that versus the cost of buying a Wacom tablet that will work.
