python-3.x - 覆盆子上的kivy opengl分段错误
问题描述
我正在使用 kivy 1.11.0.dev0 在我的 Raspberry3 上开发一个应用程序，一切正常。上周我又买了一个树莓派，从那以后我一直试图让软件在这个树莓派上运行，但没有成功。我在两个系统上都执行了相同的步骤来让 kivy 运行：
- sudo apt-get 更新
- 来自https://kivy.org/doc/stable/installation/installation-rpi.html的安装步骤
我不知道为什么第二个不起作用。两个系统都使用 Raspbian Jessie。
工作的输出：

我也尝试sdl2用作窗口提供程序。它正在工作，但它太滞后了，对我来说似乎不是最好的解决方案。
过了一会儿，在我看来这是一个 OpenGL 问题。更改 raspi-confg 会产生以下结果：
OpenGL = G1 GL (Full KMS): 结果：
黑屏，不工作，甚至没有在 SSH 上使用“startx”或更改 GPU 内存OpenGL = G2 GL (Fake KMS)： 结果：DEBUG = ... * 未能添加服务 - 已在使用？
OpenGL = G3 Legacy： 结果：DEBUG = ... 分段错误
我尝试了很多东西，比如sudo BRANCH=next rpi-update*使用旧图像、新图像、python3.5 等多次更新固件或重新安装所有东西。
从现在开始，我不知道要修复此错误。当然，我可以克隆第一个图像，但我的目标是拥有一个新的、“干净”的图像
编辑
就像在https://github.com/kivy/kivy/issues/6007中讨论的那样，问题是 Raspbian 的新版本/更新。我切换回旧版本，现在运行良好！
另一种解决方案可能是使用
os.environ['KIVY_GL_BACKEND'] = 'gl'
解决方案
