Ubuntu + Android as a second screen, how to make the cursor work?

Question

Python

Such a problem:
I set up a bunch of Ubuntu (17.04) + Android (5+, it seems. Galaxy Tab 8.4) for the tablet to work as a second screen, according to the scheme described here: https://habrahabr.ru/post/169003/
I set it up according to the second method , because moving windows between screens is important. (x11vnc)
Everything seems to start, but the cursor on the tablet screen is strictly in the center. Moreover, it monitors mouse movements and changes the view, for example, when dragging a window, entering text or scaling windows, but does not move.
How to fix?

Answer 3

I always recommend the book "python. To the heights of mastery". This is the best book to delve into.

Answer 4

Yes, a common problem of all courses and books: first they explain the basics, and then immediately some kind of framework like Django or Flask. Without good skills in the language itself, these are quite complex topics. Therefore, after reading the book, or better in the process, you need to solve algorithmic problems in order to strengthen your skills. There are good problems at https://py.checkio.org/, https://www.codewars.com/, https://shultais.education/courses/python-3 (if in Russian). After you get your hand in tasks and language, you can fit into the project. You don't need a book or course for this. You take the topic that interests you and you program. At one time, I started with a library for generating pdf invoices for paying for an apartment, when there were no management companies yet and I had to stand in line to pay for a communal apartment :)
