Ubuntu 20.04 和 18.04 中未检测到内置网络摄像头,也没有 /dev/video*

我刚刚升级到 20.04,但我的相机仍然无法工作。正如标题所述,未检测到网络摄像头,也没有 /dev/video*。我使用的是 HP ENVY13。我尝试了以前帖子中的许多解决方案(大多数与此类似更新至 14.04 版后未检测到集成网络摄像头),但目前没有任何效果。我尝试了相机键(我的情况是 f4),重新安装了 cheese,重新安装了 uvcvideo,但没有任何效果。

以下是一些初始输入:

我不知道接下来该怎么做。有什么想法吗?谢谢!

我还遇到了一个问题,即无法检测到集成网络摄像头(没有 /dev/video*),并尝试了您链接的帖子中的答案。我的工作笔记本电脑没有该按钮,但有一个 BIOS 设置可以启用摄像头,但它是关闭的。

我重新启动并进入 Bios 设置(F12),对我来说,设置位于:
系统配置 > 杂项设备 > 启用摄像头

我甚至不知道这个选项的存在,可能需要检查一下你的系统。
