Question

我在beaglebone背面安装了Ubuntu 14.04（Trusty）。我通过像这样的vnc会话连接到我的beaglebone black：

On Beaglebone：vncserver：1 -geometry 1024x768 -depth 24

以下是beagle bone上的Xorg配置： “监视器”部分标识符“内置默认监视器” EndSection

Section "Device"
    Identifier      "Builtin Default fbdev Device 0"
    Driver          "modesetting"
    Option          "HWcursor"      "false"
EndSection

Section "Screen"
    Identifier      "Builtin Default fbdev Screen 0"
    Device          "Builtin Default fbdev Device 0"
    Monitor         "Builtin Default Monitor"
    DefaultDepth    24
    Option          "AddARGBGLXVisuals" "True"
EndSection

Section "ServerLayout"
    Identifier      "Builtin Default Layout"
    Screen          "Builtin Default fbdev Screen 0"
EndSection


Section "Module"
    Load            "extmod"
    Load            "glx"
EndSection

当我运行我的kivy程序时，我收到以下消息：

我无法弄清楚为什么我收到错误[错误] [Window]无法使用pygame [错误] [窗口]模块引发了一个重要错误：“无法找到匹配的GLX visual”

这是因为我正在运行vncserver吗？或者我遗漏了一些东西（libs / modules）的BeagleBoard。

我安装了以下内容：libgl1-mesa-glx：armhf libswt-glx-gtk-3-jni libxcb-glx0：armhf libva-glx1：armhf libqt5opengl5：armhf

另外，当我执行以下操作时，我得到关于GLX visual的相同错误：

ubuntu@arm:~$ python

Traceback (most recent call last):

pygame.error: Couldn't find matching GLX visual
>>>

提前感谢您的帮助！

更新：Stackexchange不会让我回答我自己的问题......所以用解决方案更新我的问题：

我发现了这个问题。 vncserver不提供gl功能，而是使用x11vnc。

x11vnc -display：0 -forever -bg -repeat -nowf

我没有使用密码文件，它会抱怨这个...但现在我可以使用我的beagleboard并使用GL运行kivy应用程序。

kivy：该模块提出了一个重要错误：“无法找到匹配的GLX visual”
