升级至 18.04 后集成网络摄像头不工作

我购买了一台二手联想 Z370，它成功运行了 Ubuntu 12.10。我进行了全新安装，删除了 18.04 并重新安装了它。但我的集成网络摄像头无法正常工作。

  1. 奶酪告诉我未找到设备

  2. 我已经运行sudo apt-get install libsbigudrv2 libsbigudrv0并收到以下消息

    Reading package lists... Done

libsbigudrv0 is already the newest version (5:0.5-0ubuntu10).
libsbigudrv2 is already the newest version (2.0.0-0ubuntu1).

  3. 我也运行过ls -ltrh /dev/video*，得到的结果是

    ls: cannot access '/dev/video*': No such file or directory

  4. 我也运行了sudo apt-get install cheese build-essential linux-headers-``uname -r` 我得到的是

  5. 我还看到我的钥匙上有一个相机图标Esc，我按下了Fn+ Esc，但我无法检测是否发生了什么。我可以报告的一件事是/dev/video仍然不可用。

  6. 运行lspci收益率

那么，如何让网络摄像头工作呢？

编辑1：根据 Martin 的输入运行了更多命令。

  1. lsusb给出

    Bus 002 Device 007: ID 0489:e00d Foxconn / Hon Hai Broadcom Bluetooth 2.1 Device
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

  2. dmesg | grep uvc什么也没给出。

  3. dmesg | grep uvc运行后 检查sudo modprobe uvcvideo结果

    [ 2901.557462] usbcore: registered new interface driver uvcvideo

  4. 奶酪仍然不起作用。

编辑2：网络摄像头莫名其妙地开始工作了。我猜是前几个月的软件更新让它变得可能了。我第一次注意到这一点是在运行 zoom 时。网络摄像头工作了大约 5 秒后就停止工作了。所以我打开了 cheese，网络摄像头工作了大约半分钟（质量很差），但后来就停止工作了。

答案1

为了可能拯救像我一样浪费时间的人，有些笔记本电脑有一个键盘按钮来打开网络摄像头，比如我的 Clevo P150EM，Fn+F10

我还必须重新启动 Cheese 来检查它是否正常工作。

答案2

奇怪的是，我遇到了与 Ubuntu 18.10 之前安装时一样的问题，它应该在开箱后运行。这可能对你有用，就像对我有用一样。我在终端中输入了 lsusb，但它无法识别我的相机。Cheese 和其他程序也无法识别它。如果我想初始化我的相机，我必须上网到聊天网站才能出现对话框。在同意在 Firefox 上使用我的相机后，突然间它可以访问之前所有无法访问的尝试。如果这对您有用，请告诉我。
