Kivy hello world脚本在Ubuntu 14.04上产生黑屏

运行此处的基本 hello world 脚本 -https://kivy.org/docs/guide/basic.html生成以下日志并弹出一个完全空白和黑色的窗口。

我已经在 Ubuntu 14.04 上安装了 Kivy 1.9.1 和 python 2.7，我也尝试过升级我的图形驱动程序，但这并不能解决问题。

日志：

以下是代码：

import kivy
kivy.require('1.9.1') # replace with your current kivy version !
from kivy.app import App
from kivy.uix.label import Label
class MyApp(App):
    def build(self):
        return Label(text='Hello world')
if __name__ == '__main__':
    MyApp().run()

xclip使用安装sudo apt-get install xclip。另外，检查您的gtk版本。将其更新至gtk3。

编辑：也安装 ffmpeg。
