![我的笔记本电脑集成网络摄像头在 Ubuntu 16.04 中无法工作](https://linux22.com/image/1164773/%E6%88%91%E7%9A%84%E7%AC%94%E8%AE%B0%E6%9C%AC%E7%94%B5%E8%84%91%E9%9B%86%E6%88%90%E7%BD%91%E7%BB%9C%E6%91%84%E5%83%8F%E5%A4%B4%E5%9C%A8%20Ubuntu%2016.04%20%E4%B8%AD%E6%97%A0%E6%B3%95%E5%B7%A5%E4%BD%9C.png)
我安装了一款使用网络摄像头的名为 motion 的软件,但我没有足够的耐心去学习如何使用它,于是使用 sudo apt purge 卸载了它。但卸载后我的网络摄像头就停止工作了。
lsusb -v | grep cam
给出:
Couldn't open device, some information will be missing
Couldn't open device, some information will be missing
Couldn't open device, some information will be missing
我尝试跑步
sudo modprobe -r uvcvideo
进而
sudo modprobe uvcvideo
但它仍然不起作用。
奇怪的是,摄像头的 LED 灯仍然亮着。是不是有间谍软件和软件干扰了它?
我无法将它与 cheese 一起使用,也无法在 chrome 中与 google hangouts 一起使用。我还尝试过重启电脑。

答案1
我终于搞明白了。我安装了一个较新版本的 Linux 内核,但缺少一些模块。所以我只需通过双启动菜单返回到以前的版本,问题就解决了。
