Oof! It was a fun little hunt to get this tablet decent under Linux with multi monitors. What I wound up having to do was after installing the Xorg OpenTabletDriver, then I have to manually start the service with “systemctl --user enable opentabletdriver.service --now”. Then after that use a program called xinput as per this document “xinput map-to-output <tablet id> <output name>”, which in-of-itself has its own quirks. The ouput id had to be quoted, “HDMI-0” and I had to wait til the opentabletdriver was loaded and select the id=16 option instead of any of the others.
At least the tablet maps to one monitor, that will make it so so so much easier to draw with.
