Some features unavailable?

I’m just running my first game script and after opening the window I see this in terminal:

Known pipe types:
(all display modules loaded.)
:device(warning): /dev/input/event12 is not readable, some features will be unavailable.

What can I do about this ? Do I need to change permissions ? I should be able to close the window with ESC but it doesn’t work. I’m closing it with cross in the right-top corner. I’m on Ubuntu 18.04

It means that one of your input devices is not configured to be accessible by Panda. You can safely ignore this warning.

To make your application close with the escape key, you can add something like this:

base.accept('escape', sys.exit)

Thank you for a such prompt response ! Nice support.
