Jam*_*nan 2 google-chrome webcam camera
今天我使用 Chrome 浏览器参加了 Google Hangout。浏览器报告“未检测到相机”。这很令人惊讶,因为在我拥有这台机器的四年半里,我大约每两个月使用一次相机。我最后一次使用相机是在 2018 年 4 月 26 日或 5 月 31 日。当 Ubuntu 提示时,我非常勤奋地应用软件更新。
我检查了系统设置,但没有相机图标。此外,当我在搜索窗格中输入“相机”和“未检测到相机”时,什么也没有出现。我搜索了 Chrome 的帮助,其中的建议归结为“重新启动计算机”。重启并没有解决问题;相机仍未被发现。
这是我的系统信息:

另一位用户提出了这个问题,提供了 lspci 的输出(我将在这里做),但没有得到回应。

解决方案来自这里:Fn+<Cam>在我的机器上是Fn+F6。 “[h]按下笔记本电脑上的网络摄像头功能键会在硬件中添加/删除设备,就像物理连接/断开连接一样。” 一旦我这样做了,我得到了这些发现:
$ ls -l /dev/video*
crw-rw----+ 1 root video 81, 0 Jun 28 21:38 /dev/video0
$ lsmod | ack '^video\b'
