(适用解决)
我曾经在我的Ubuntu 14.04计算机上运行kivy应用程序。基维确实跑得很好。 然后我决定从Ubuntu 14.04升级到Ubuntu 16.04。 升级过程(在线)很顺利。
不幸的是,自升级以来,我所有的kivy应用程序都不想再运行了。他们停止了这个错误:

注意:kivy是通过virtualenv中的pip安装的。
我决定销毁我的virtualenv并重新创建并通过pip install重新安装。这是我的点子清单:

重要提及:
我确实按照以下注意事项发现: https://kivy.org/docs/installation/installation-linux.html#dependencies-with-sdl2
所以我做的是:
不幸的是,当我启动一个kivy app时,它会停在上面的错误中。
我尝试了别的东西:
我通过Ubuntu软件包安装了kivy:同样的错误!!!
所以我的想法是:
可能存在一些东西(库/某些库)阻止kivy应用程序运行,但是什么?
总结:
两种方法都以相同的错误结束。
无论我做什么,我总会得到同样的错误。
任何帮助真的很感激! 感谢
PS:这是发布的完整输出。有这一行:
x11 - ImportError: No module named window_x11
我不知道它是否有帮助。

解决
自升级以来,图形系统(OpenGL)被破坏了。所以我为我的Nvidia卡安装了正确的驱动程序,现在一切正常!
