Thinkpad X1瑜伽OLED亮度

Question

我运行Ubuntu17.10与GNOME (Wayland)的联想X1瑜伽OLED。

我相信这个Ubuntu安装是几年前从Ubuntu16.04开始的。自从系统第一次安装以来，我就一直在运行GNOME。-这意味着我可能在我的系统中留下了一些我完全忘记的古老的覆盖。

问题是:我在日记中从gnome设置-守护进程中获得了很多错误消息：

我在“设置”面板中禁用/启用了“自动亮度”控件，它似乎不会更改任何内容。

在Ubuntu 18.04 (基于xorg)中观察到类似的情况。使用gsettings set org.gnome.settings-daemon.plugins.power ambient-enabled false，通过关闭自动亮度来解决问题。
