为什么 sddm 中没有显示选择 unity 8 的选项？

我决定在我的 kubuntu 系统上尝试 unity8。

重新启动系统时，sddm 未显示选择 unity 8 的选项。我在这里做错了什么？

答案1

sddm 只能启动 X11 和 Wayland 会话。要么要求 Canonical 将 Unity8 移植到 Wayland，要么切换到 Ubuntu 现在使用的任何登录管理器——可能是 LightDM。

答案2

您的显示管理器（在您的情况下为 SDDM）需要支持 Mir 显示服务器。Canonical 仅支持其显示服务器项目（LightDM），其他项目需要添加自己的支持。
