Tablet Problems with Synfig

I recently just downloaded Synfig and was so excited to use it and start learning, but my tablet basically wont work at all with it. I have the Huion Inspiroy H640P. If I try to use the stylus, it freezes and wont move once Synfig is open. I’ve tried to use the Input Dialogue for the stylus, and both enabling screen or window wont do anything. I’ve looked at the other forum posts as well, and nothing seems to be working. Help?

Hi! Sorry, in general we provide support for Wacom-branded tablets only.

Still, you can try some workarounds -

Technical details: Our tablet support comes from GTK library. If you want to have complete support of Huion tablets, please make a request to GTK guys.
