Apr 22, 2009  1. Yes your graphics card must say it supports OpenGL. But let me add that pretty much *all* graphics now support OpenGL these days. The issue they many openGL programmers face is not whether openGL is supported on a graphics card, but which *version* of openGL is supported. The most recent being openGL v2.1.

The current 'gold standard' even in 3D applications is still OpenGL 2.1 for viewport display. Some of them use OpenGL 3.0 and specific features like Maya's 'Viewport 2.0' even higher. At this point I'm not aware that any professional app permanently uses OpenGL 4.0, but of course one year down the road they all may.

I have decided to do some programming in Kivy cross platform and installed Kivy on my computer successfully. The problem is that when I run my code, I get this error:

And this error box pops out:

I have checked OpenGL version of my GPU via GPU Caps Viewer verifying me up to OpenGL Version 2.1, but Kivy somehow doesn't detect OpenGL 2.1 and defaults to GDI Generic from Microsoft instead. I did some research on internet and found out that best way to resolve this problem is to update your graphical card's driver from your graphical card manufacturer, but this didn't work in my case.

I have updated my graphic drivers (I am running NVIDIA GeForce GT 435M on 64-bit Windows 8).

My question is: Is there a way to let Kivy switch from GDI Generic driver to NVIDIA driver? Or is there a problem somewhere else?

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

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>

Angle backend for py3.5+

It works perfectly on windows 10 and its solution for above problem. Multisample won't work in my case

I use Python 3.6 and Windows 8.1. Works on Windows 10 also.
this solution solve the problem in most cases :
.
1. Right click on This PC then open Properties .
2. Go to Advanced system settings .
3. Click on Environment Variables .
4. Click on New in User variables for --- .
5. Put KIVY_GL_BACKEND in Variable name .
6. Put angle_sdl2 in Variable value .
7. Restart Python .

Here is a YouTube video showing these steps :https://www.youtube.com/watch?v=ATK9w2AiDeM

If u still have the problem try this:

its worked for me (win10, opengl3.1, py3.6)

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.

Change multisamples key value in config file (%HOMEPATH%.kivyconfig.ini for me) from multisamples = 2 to multisamples = 0.

put this in your code and it ll work

from kivy import Config

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

in addition to setting multisamples to 0,
