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.
I don’t think you’re going to find much cheaper for a full fledged tablet format machine with a high res capacitive touchscreen @165hz that will render what you’re asking for. This is the exact package you’re looking for though. Maybe wait for a sale.
Pretty sure my XP Pen’s refresh rate isn’t 165hz, and I find it perfectly fine to work on, so I don’t need something with such a high refresh rate.
At about 13 inches the resolution of the screen doesn’t need to be more than 1080p either.
