当我在 Ubuntu 14.04 LTS 系统上安装 GNOME 时，GUI 出现了问题。安装 Gnome 后还出现了其他问题。
如果您知道如何彻底卸载 gnome，以及如何让 Ubuntu 14.04 LTS 恢复到全新安装状态，请帮助我。即使在我卸载 Gnome 之后，问题仍然存在。
答案1
我建议使用tasksel基于 ncurses 的工具，它允许您安装软件包组（用于 debian 和 ubuntu 最小安装程序）。
从您的终端启动该工具后，您将获得一个软件包组列表。要卸载 gnome，只需取消勾选（使用空格键），ubuntu-gnome-desktop这样一旦应用，您便会得到一个干净的状态。
