问题描述
我的 Ubuntu 桌面在哪里？它的启动和运行始终默认为终端屏幕，如果我按 Ctrl + Alt + F7 仍在终端 Ctrl + Alt + F1 仍在终端。
没有 GUI，我该如何恢复它？

似乎解决这个问题就像火箭科学一样，它是不确定的。我没有浪费时间调试它，而是终于 re-install 了 ubuntu。
最佳方法
尝试这个。只需按键盘上的 Ctrl + Alt + T 打开终端。打开后，运行以下命令：
sudo apt-get install --reinstall ubuntu-desktop
次佳方法
按照以下说明操作：
-
sudo dpkg --configure -a -
sudo apt-get install --reinstall ubuntu-desktop -
重新启动计算机并转到桌面
第三种方法
当我在我的机器上遇到这个问题时，我只需删除 /etc/X11/xorg.conf 并重新启动系统。但是 – 我总是做备份！ 🙂
第四种方法
你以前有什么显示管理器？使用 Ctrl + Alt + F1 以 root 身份进入保护模式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
如果您的显示管理器与 gdm 不同，请键入 kdm 或 lightdm 。
