Config Kivy > Invert input for y axis

Question

I am trying to setup a "off-brand" touchscreen on a Raspberry Pi3 and I am having some trouble when I run my python/kivy program, visually everything is fine, but whenever I need to move a slider, push a button or whatever. the input y-axis is inverted, note that it works fine when i run this on my windows machine As you can see the input for the buttons are inverted on the y axis

I do know this exists and I have tried it, but it did nothing to solve the problem (In my case). https://stackoverflow.com/a/34344458/7522859

And I have tried to fix it in the config file under (in my case) (.kivy/config.ini), and as you can see it reads the invert_y option but does nothing with both 1 and 0 as its values.

So the question is how do I invert the Y-axis for the input in the kivy config file. I have also taken a look at this and I didn't really understand it that well, maybe I am just stupid.

Sorry if this post is bad. Its my first post and English is not my native language.

Answer 1

I got it to work, finally.

I changed the line 417 in the hidinput.py under:

/usr/local/lib/python2.7/dist-packages/kivy/input/providers/hidinput.py

Credit: How do if invert touch input in Kivy

and set the config:

~/.kivy/config.ini

under [input]

ADS7846 = hidinput,/dev/input/event2,invert_y=0
