This question already has an answer here:
I would like to learn about the applications that exist in a certain class of software on Ubuntu. But asking a question like that is a software recommendation and is against the rules of Ask Ubuntu. Is there a way to ask a question about that on Ask Ubuntu in a way that will follow the rules of the site and be useful and informative for others in the long term?
I would like to learn about drawing and painting software that is available on Ubuntu, or may become available soon (I believe there isn't much today; is there any hope for the better?). I'd like to use Ubuntu on Microsoft Surface Pro line of tablet/laptops and draw on it.
This class of software I have in mind includes tools such as:
All of which are not available o Linux.
