像标题一样，建议仍然存在吗？
我尝试在安装了Guest Additions的VirtualBox中的Ubuntu 16.04上运行Unity 8。当我从LightDM登录到Unity 8会话时，它只会加载黑屏，然后注销或冻结。我还通过以下命令安装了Unity 8：
sudo apt install unity8-desktop-session-mir
sudo add-apt-repository ppa:ci-train-ppa-service/stable-phone-overlay
sudo apt update && sudo apt upgrade
也许我错过了要安装的东西，但是当我尝试在Unity 7之上的终端中运行Unity 8时，我得到了同样的东西。但是，我得到以下输出：
mathcubes@Ubuntu-VM:~$ unity8
Mode argument was not provided or was set to an illegal value. Using default value of --mode= "full-greeter"
file:///usr/share/unity8//OrientedShell.qml:21:1: plugin cannot be loaded for module "Unity.Screens": Cannot load library /usr/lib/x86_64-linux-gnu/qt5/qml/Unity/Screens/libunityscreensplugin.so: (libqpa-mirserver.so: cannot open shared object file: No such file or directory)
import Unity.Screens 0.1

我可以运行Unity 8吗？兼容吗？
