除了我运行的默认 X 服务器之外，tty1我还想从 Linux 容器中启动另一个服务器。
在终端2(Ctrl+Alt+F2) 我登录，然后运行sudo lxc-start -n c --foreground.
然后，从我执行的容器内DISPLAY=:2 startx -- :2获取这些消息/错误：
_XSERVTransSocketCreateListener: failed to bind listener
_XSERVTransSocketUNIXCreateListener: ...SocketCreateListener() failed
_XSERVTransMakeAllCOTSServerListeners: failed to create listener for unix
