使用 aptitude 安装 ubuntu-desktop 后无法移动或调整窗口大小

我有 Ubuntu 16.04：

root@ubuntu:~# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.5 LTS
Release:    16.04
Codename:   xenial

root@ubuntu:~# uname -a
Linux ubuntu 4.15.0-45-generic #48~16.04.1-Ubuntu SMP Tue Jan 29 18:03:48 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

我遇到了无法加载 GUI 桌面的问题，所以我已安装它与aptitude：

aptitude install ubuntu-desktop

但是在加载 GUI 之后，只剩下桌面，没有栏和所有菜单，并且我无法移动\调整窗口大小。 在此处输入图片描述

我尝试重新安装ubuntu-desktop但apt-get失败了：

root@ubuntu:~# apt-get install --reinstall ubuntu-desktop
