不用说，nvidia-settings 和 KDE 的显示设置对此不起作用。
我有三个显示器，一个内置在笔记本电脑中，另外两个通过 DisplayPort 连接。我希望重新排列它们的默认排列方式。
当我在 nvidia-settings 或 KDE 的显示设置中进行相应更改时，更改未应用。重新启动后，系统仍显示与之前相同的设置。
我知道我的更改产生了一些影响，因为登录屏幕的排列很合理。只是当我登录时，它似乎忽略了我的设置。
下面是我的 xorg.conf 和 的输出nvidia-settings -q CurrentMetaMode。请告诉我是否还有其他信息需要提供。我已经花了三个小时研究这个问题，这是我第一次尝试配置 X，所以我不是很清楚我到底在做什么。谢谢！
$ nvidia-settings -q CurrentMetaMode
