Kivy does not detect OpenGL 2.0 [closed]

Answer 1

This seems to be a known bug in the current version of kivy and is already reported in their issue tracker. So I guess there is no (easy) way to solve this problem. Switching back to an older version might help.

Answer 2

I remember having worked around this bug by changing the color depth of the screen (from 16bit to 32bit or vice versa).

Answer 3

As a quick workaround, try this.

# Keep these two lines until you find what the real solution is
import os
os.environ['KIVY_GL_BACKEND'] = 'angle_sdl2'

from kivy.app import App
App().run()

Answer 4

For old embedded graphics like Intel GMA 965 at Windows 10:

in addition to setting multisamples to 0,

Answer 5

On windows 7 pro 32bit adding Config.set('graphics', 'multisamples', '0') solved the error for me. (Update: This is also works on Windows 10.)

import kivy 
kivy.require('1.9.1') # replace with your current kivy version !

from kivy.app import App
from kivy.uix.label import Label

# add the following 2 lines to solve OpenGL 2.0 bug
from kivy import Config
Config.set('graphics', 'multisamples', '0')


class MyApp(App):

    def build(self):
        return Label(text='Hello world')

if __name__ == '__main__':
    MyApp().run()

After the change, the OpenGL version is reported correctly:

[INFO ] [GL ] GLEW initialization succeeded

[INFO ] [GL ] OpenGL version <2.1.0 - Build 8.15.10.2281>

Answer 6

If you still have the problem try this:

import os
os.environ['KIVY_GL_BACKEND'] = 'angle_sdl2'

It worked for me (Windows 10, OpenGL 3.1, Python 3.6).
