Lenovo ThinkPad T590 集成摄像头无法在 Ubuntu 18.04 上运行

标题中描述了我的问题，我在谷歌上搜索了两个晚上，但对问题无能为力。

lsmod | grep uvcvideo 命令什么也没显示，但是当我用 USB 插入外部摄像头时，uvcvideo 模块加载并且外部摄像头在奶酪和网络摄像头应用程序中都可以正常工作。

如果我uvcvideo用modprobe命令加载仍然没有任何反应。

$ sudo modprobe uvcvideo

$ lsmod | grep uvcvideo

看起来集成摄像头刚刚被禁用或类似的东西，所以我检查了 BIOS 中是否启用了摄像头，是的，它已启用。

也很遗憾，但我不记得在安装 Linux 之前我是否在 Windows 上检查过摄像头，但实际上我怀疑它是否会坏掉。

也许有人知道我应该怎么做才能让相机栩栩如生？
