我在 Hyper-V 中创建的虚拟机上安装了全新的 Debian。我选择安装 KDE 环境，通常不会出现任何问题，因为系统总是直接加载到 DE。但在这种情况下不会出现问题。
此时系统启动后会进入一个黑色的登录界面，并带有终端输入。
它提示登录并输入密码，成功接受。之后，我就可以自由地从终端做任何我想做的事情了。如果我手动输入startx命令，我甚至可以进入 KDE 桌面。
我不知道是什么导致了这种情况。我四处寻找解决方案，这种情况主要发生在您有多个 DE 或没有 DE 时，但我只有 KDE。而且系统似乎完好无损，是从官方 ISO 安装的。
当我尝试安装新的登录屏幕时，出现网络错误，然后系统设置突然崩溃，并显示以下日志：
Application: System Settings (systemsettings5), signal: Segmentation fault

你能帮我解决这个问题吗？我不想每次启动系统时都手动启动 KDE。
答案1
以 root 身份尝试以下命令：
systemctl set-default graphical.target
它将默认启动目标更改为图形环境。它相当于runlevel 5System V 命名法。
要恢复此设置，您可以设置multi-user.target。
