Question

我有一个脚本使用 java 连接到在 localhost 的端口 10.0 中显示 X11

但我总是得到这个错误

我已经尝试了一切来解决这个问题，例如:

export DISPLAY=:10.0
export DISPLAY=localhost:10.0

我也尝试了端口 0.0，但总是遇到同样的错误

尝试xhost之后

xhost +local:all
xhost:  unable to open display ""
xhost:  unable to open display ":10.0"

我该如何解决这个问题我认为 X 服务器没有运行，所以我尝试了 startx 它说它在那个端口运行

我的系统是Ubuntu server edition 10.04
