I bought an xp-pen pro (15 inchish) for my daughter xmas before last and she uses it almost every day on her steamdeck desktop.
Edit: Derp. I read your comment after posting based on the thread title. So I guess this is a +1 for xp-pen pro if any future reader is looking for an attached drawing tablet for linux.
