I have a 2nd generation XP Pen Artist 13. It’s a great tablet and I’ve managed to make it work with my Steam Deck too.
But…
It’s basically an external monitor with pressure sensitive surface, so still less portable than an actual stand alone table. So I’m wondering if there is a tablet with a pressure sensitive screen and battery free pen that either comes with Linux or can install Linux on.
The programs I use for making art are Krita, Gimp, and Blender 3D.
Wifi works now, the wiki is out of date.
However, the Pinetab 2 does not have the screen layer for stylus support. See the FAQ
