因此,我安装了全新安装的 Ubuntu 18.10,并且确实有 ubuntu gdm3 的正常新登录屏幕。我一直在下载 gnome 主题,我注意到在完成所有操作后(不知道是否是由于安装新主题),当锁定计算机时,我仍然可以看到正常的锁定屏幕,而当我向上滑动时,我可以看到标准的登录屏幕:
但是现在当我点击“以其他用户身份登录”时,情况变得很奇怪,我得到了一种新的不同类型的登录屏幕,这也是在徽标加载屏幕之后启动 ubuntu 时出现的(在这个登录屏幕上,点击也不起作用!):
编辑:抱歉,我忘了添加一个问题 - 这是什么(这是正常的吗?)以及如何将其恢复为默认值?
我会很高兴得到您的帮助谢谢!

关于自动模式和手动模式:
automatic mode
When a link group is in automatic mode, the alternatives system ensures that the
links in the group point to the highest priority alternative appropriate for the
group.
manual mode
When a link group is in manual mode, the alternatives system will not make any
changes to the system administrator's settings.
