gest's Issues

Building locally and running scroll demo fails on Linux Mint 20 (Ubuntu 20)

This is a neat project!

I cloned the repo, ran poetry install, used poetry to run the scroll demo script and got:

Try one of the following resolutions:

 * Please make sure that you have an X server running, and that the DISPLAY environment variable is set correctly

I activated the poetry shell via poetry shell and tried again:

Running pip install gest shows an error but does actually install and then
(venv) ➜ gest-test python -m gest.examples.two_handed_scroll_and_click
works.

X-server is running and display is set

(gest-DwnxmegZ-py3.8) ➜  gest git:(master) ✗ echo $DISPLAY
:0.0

I planned on integrating with Talon as an experiment so I don't think I need pynput for that but wondered what I've missed to make it work :-)

You should use a rubber band to have physical feedback when you do your movement.
