Read your error message! 阅读您的错误消息！ It seems fairly clear you're running the commands from an SSH session or similar, since DISPLAY isn't set. 由于未设置DISPLAY，因此从SSH会话或类似程序运行命令似乎相当清楚。 Set it to the correct value (check what X11 sockets are in /tmp; you probably want ":0"). 将其设置为正确的值（检查/ tmp中的X11插槽;您可能需要“：0”）。
DISPLAY=":0"; export DISPLAY
You'll also want to set XAUTHORITY so x11vnc can connect! 您还需要设置XAUTHORITY，以便x11vnc可以连接！ Dupe of this question. 杜佩这个问题。
