Directfb显示在vnc上面的问题
请问directfb如何支持vnc,我是在开发板上移植的dfb和libvncserver,现在客户端链接上后显示的是一个黑色的界面其他什么都看不到,我们现在需要dfb同时显示在framebuffer和vnc上,不知到还需要什么配置吗?有做过相关开发的吗?交流一下
现在我已经将dfb移植到板之上了,并且配置dfb显示到vnc上但是在运行时出错

在屏幕上显示是黑色的,并且不断的打印上面的这些内容,这时候我试用vnc客户端连接不上。
我启动了一个自己用libvncserver写的简单服务器,使用vnc可以链接了但是看到的也是黑色的,什么都看不到!有做过相关开发的吗?
不知到为什么
