我有一个脚本使用Java连接到本地主机的端口10.0中显示X11

但是我总是得到这个错误

java.lang.InternalError: Can't connect to X11 window server using 'localhost:10.0' as the value of the DISPLAY variable.

我已经尽力解决这个问题，例如：

export DISPLAY=:10.0
export DISPLAY=localhost:10.0

我也尝试了端口0.0，但总是得到相同的错误

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 Server没有运行，所以我尝试了startx它说在该端口运行

我的系统是Ubuntu服务器版本10.04
