由于javafx支持Raspberry PI。我想在帧缓冲区中运行FX应用程序。我正在使用Lubuntu LCD显示图像。
当我尝试运行JavaFX应用程序时
java -Djavafx.platform=eglfb Hello.jar
我收到以下错误
我正在使用java8嵌入式硬件。
libEGL warning: DRI2: failed to authenticate

经过几次研究后,您应该考虑重新安装OpenGL ES和GTK。初始化期间出现问题,Java无法呈现应用程序。
在运行时使用的Java版本可能是一个问题,必须是Java 8.让我们检查一下系统使用的默认java版本:
ls -l /usr/lib/jvm
如果版本不正确,可以使用以下命令进行更改:
sudo update-alternatives --config java
您还可以使用以下命令检查java是否可访问:
java -version
您可以使用以下选项获得更多信息:
