x11vnc 错误：“找不到程序“Xvfb”。”

最近我一直在通过互联网访问一台 Ubuntu 机器。我一直使用以下命令连接并启动 x11vnc 服务器

ssh [email protected] -p 2222  -L 5903:localhost:5900 "x11vnc -display :0 -noxdamage - create -usepw -once"

然后我会localhost:5903在 MacBook 的原生屏幕共享程序中打开。

几天来，一切都运行良好，直到刚才，在我升级了 Ubuntu 之后。现在命令失败，并出现以下错误：

The program "Xvfb" could not be found in PATH and standard locations.
You probably need to install a package that provides the "Xvfb" program.
Without it FINDCREATEDISPLAY mode may not be able to create an X display.

有人知道发生了什么事以及如何解决吗？

答案1

xvfb在终端中安装sudo apt-get install xvfb -y。Xvfb——当没有物理显示器连接到系统时，“X Virtual FrameBuffer”模拟/“伪造”X 显示。它的常见用途是在无头系统上运行需要显示器的程序。
