新的Kivy用户在这里...
我在仿生Ubuntu中运行Kivy时遇到问题。简单的Hello World应用程序会引发分段错误。窗口以部分绘制的方式在设备屏幕上弹出：框架和标题栏，但没有背景，并且在kivy控制台输出中出现分段错误后立即消失。
我的安装是：
Python：
import os
print(os.path)
from kivy.app import App
class MyApp(App):
pass
if __name__ == '__main__':
MyApp().run()
最初，我遇到“无法找到任何有价值的Window提供程序”的问题。我必须添加一些未加载的必需软件包（主要与 libsdl 相关），然后运行glxinfo并使用最后一个ID（0x16a）更新环境： < / p>
export SDL_VIDEO_X11_VISUALID=0x16a
这使我摆脱了“没有有价值的窗口”错误，但仍然没有喜悦。现在它可以断层了。
我的 Kivy日志显示：

问：接下来我应该寻找什么？我是否可以提供其他信息，以帮助某人指出正确的方向？似乎我真的很接近，但是认为这是GL或sdl问题，因为我不得不加载似乎不在发行版中的软件包？
谢谢。
