屏幕自动旋转仅在实时 USB 中有效，安装后无效？

我是 Ubuntu 新手，刚刚将其安装在带触摸屏的联想 N23 上。

自动旋转功能在实时媒体 USB 上运行良好，并且具有锁定和解锁选项，但在完全安装后，我没有看到旋转，菜单中也没有任何内容。

似乎我可以使用 Superkey+O 锁定和解锁旋转，但这只显示如果没有锁定，则即使没有被查看也不会旋转。

确实需要一些帮助。

硬件：联想 N23 WinBook

操作系统：Ubuntu 22.04

如果我运行，systemctl status iio-sensor-proxy我会得到以下结果：

 iio-sensor-proxy.service - IIO Sensor Proxy service
     Loaded: loaded (/lib/systemd/system/iio-sensor-proxy.service; static)

跑步monitor-sensor让我：

$ monitor-sensor
    Waiting for iio-sensor-proxy to appear
+++ iio-sensor-proxy appeared
=== Has accelerometer (orientation: normal)
=== No ambient light sensor

并且，当我旋转笔记本电脑时，它会按预期打印：

Accelerometer orientation changed: right-up
    Accelerometer orientation changed: bottom-up
    Accelerometer orientation changed: left-up
    Accelerometer orientation changed: normal

当我把cat /proc/bus/input/devices这个打印出来时：

如果我加载到实时媒体并运行，我会得到完全相同的打印输出cat /proc/bus/input/devices，但在实时媒体中，它实际上会按预期旋转屏幕。

希望这些信息能够派上用场，真的很抱歉写了这么长的文章，因为我刚接触 Linux，所以不确定哪些是重要的，哪些不重要。
