如何解决Kivy错误:错误窗口(Window参数无效)？

Question

我安装了Kivy和Cython.我使用VirtualBox和Arch Linux与Gnome作为我的显示管理器.创建以下应用程序后,

from kivy.app import App
from kivy.uix.button import Button

class CalcApp(App):
    def build(self):
        return Button(text="Hello World")

if __name__ == '__main__':
    CalcApp().run()

我收到以下错误

[INFO   ] [Logger      ] Record log in /home/kyle/.kivy/logs/kivy_17-10-19_40.txt

如果我运行命令unset DISPLAY它按预期工作,但没有选项来最小化,最大化和关闭通常可用的窗口.

有没有办法修复此错误,所以每次打开一个新的终端窗口并让它看起来像普通窗口时,我不需要键入未设置的DISPLAY？

我的问题通过更新解决了。大约一个月后，我能够按预期使用 Kivy，没有出现任何错误。
