升级到 18.04 后集成网络摄像头不工作

Question

我购买了一台成功运行 Ubuntu 12.10 的二手联想 Z370。我进行了全新安装，删除并安装了 18.04。但我的集成网络摄像头无法正常工作。

1. Cheese 告诉我找不到设备

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

   Reading package lists... Done
   Building dependency tree       
   Reading state information... Done
   libsbigudrv0 is already the newest version (5:0.5-0ubuntu10).
   libsbigudrv2 is already the newest version (2.0.0-0ubuntu1).
   0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
   

3. 我也跑了ls -ltrh /dev/video*，我得到的结果是

   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

   Reading package lists... Done
   Building dependency tree       
   Reading state information... Done
   build-essential is already the newest version (12.4ubuntu1).
   cheese is already the newest version (3.28.0-1ubuntu1).
   linux-headers-4.15.0-29-generic is already the newest version (4.15.0-29.31).
   0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
   

5. 我还在我的Esc钥匙上看到了一个相机图标，我按下了Fn+Esc但我无法检测到是否发生了任何事情。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 的输入运行更多命令。

1. lsusb 给

   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 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
   Bus 001 Device 003: ID 0bda:0139 Realtek Semiconductor Corp. RTS5139 Card Reader Controller
   Bus 001 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 什么都不给。

3. dmesg | grep uvc运行后 检查sudo modprobe uvcvideo，它产生

   [ 2901.557462] usbcore: registered new interface driver uvcvideo
   

4. 奶酪还是不行。

编辑 2：网络摄像头神秘地开始工作。我猜前几个月的软件更新使它成为可能。我在运行缩放时第一次注意到这一点。网络摄像头工作，然后在 5 秒左右后停止工作。所以我打开奶酪，网络摄像头可能工作了半分钟（质量很差），但后来停止工作。

Answer 1

为了可能拯救像我这样浪费时间的其他人，一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 以检查它是否有效。
