![Ubuntu 16.04 LTS 中未检测到摄像头](https://linux22.com/image/1158289/Ubuntu%2016.04%20LTS%20%E4%B8%AD%E6%9C%AA%E6%A3%80%E6%B5%8B%E5%88%B0%E6%91%84%E5%83%8F%E5%A4%B4.png)
今天我使用 Chrome 浏览器参加了 Google Hangout。浏览器报告“未检测到摄像头”。这很令人惊讶,因为在我拥有这台机器的四年半时间里,我大约每两个月使用一次摄像头。我最后一次使用摄像头是在 2018 年 4 月 26 日或 5 月 31 日。当 Ubuntu 提示我应用软件更新时,我会非常认真地执行。
我检查了系统设置,但没有找到相机图标。此外,当我在搜索栏中输入“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,其中的建议是“重启电脑”。重启并没有解决问题;相机仍然未被检测到。
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。

在我的计算机上是Fn+F6
。 “按下笔记本电脑上的网络摄像头功能键可以在硬件中添加/删除设备,就像它已经物理连接/断开连接一样。” 我这样做之后,得到了以下发现:
$ ls -l /dev/video*
crw-rw----+ 1 root video 81, 0 Jun 28 21:38 /dev/video0
$ lsmod | ack '^video\b'
video 40960 2 i915,msi_wmi
非常感谢。
