我刚刚从ubuntu-20.04-桌面-amd64.iso。
经过两天的测试，我完全不喜欢它的图形界面 - GNOME Shell。
即使安装 GNOME Flashback 也无济于事。
因此，我想从我的系统中完全删除 GNOME Shell 及其所有踪迹，而无需重新安装。
只想从头开始，就像我从最小网络启动 ISO。

sudo apt install ubuntu-unity-desktop - Xfce 与 Xubuntu 一样 -
sudo apt install xubuntu-desktop^

答案2
在进行最小安装后，仅使用“lxde” [/usr/sbin/lightdm文件中的条目/etc/X11/default-display-manager]，不幸的是，在从 18.10 全面升级到 19.04 时，我得到了“gdm3”，并且这种情况一直持续到 20.04。最后我删除了“gdm3”。此外，我还必须使用sudo apt-get remove“gnome-shell”和“ubuntu-session”。之后，我用一个简单的sudo apt-get-autoremove.
