@Wolthera @helveticablanc I agree. I bought a Huion H640P myself and it works flawlessly on Linux Mint. After some initial configuration, you should be good to go.
In addition to checking the #DIGImend project (https://digimend.github.io), there are also several review sites you can check for recommendations. (I used https://www.addictivetips.com/buying-guides/linux-drawing-tablet.)
