我在笔记本电脑上安装了 ubuntu 16.04。开机并登录时，屏幕上显示壁纸和鼠标光标，没有面板、仪表板或打开窗口等功能。启动 Unity 桌面大约需要 5-15 分钟。我最初以为它根本无法加载，就像这个问题一样：Unity 无法加载，没有启动器，也没有出现 Dash。

答案1
您是否尝试过链接中解释的所有上述方法。
您还可以尝试：
apt-get --reinstall install unity
如果不成功，那么
apt-get install ubuntu-desktop
答案2
问题在于有很多点文件。自从我将很多（大约 1 GB）应用程序移至 以来.local/share/applications，Unity 变得太慢了。
