解决这个问题似乎像火箭科学一样困难，它还没有解决。为了不浪费时间调试它，我最终重新安装了 ubuntu。

答案1

试试这个。只需按下键盘上的Ctrl+ Alt+T即可打开终端。打开后，运行以下命令：

sudo apt-get install --reinstall ubuntu-desktop

答案2

请遵循以下说明：

  1. sudo dpkg --configure -a
  2. sudo apt-get install --reinstall ubuntu-desktop
  3. 重新启动计算机并进入桌面

答案3

Ctrl您之前使用过什么显示管理器？使用++以Altroot身份进入保护模式F1然后尝试重新安装以下软件包：

apt-get install --reinstall xorg-xserver*
apt-get install --reinstall gdm
apt-get install --reinstall unity

如果您使用的显示管理器不同于 gdm，请输入kdm或lightdm。

我也曾经遇到过这种情况 - 关于 nvidia-drivers......

答案4

对我有用的是以下两个命令，然后重新启动

sudo apt install xorg
sudo apt-get install --reinstall ubuntu-desktop
