Ubuntu 18.04 无法识别我的网络摄像头。请帮帮我

我的摄像头有问题。我使用的是 Ubuntu 16.04，这个操作系统可以看到我的网络摄像头。然后我将操作系统更改为 Ubuntu 18.04，现在它看不到网络摄像头。问题出在哪里？我还尝试了 16.04 和 18.04 liveCD，但只有第一个可以看到我的网络摄像头。

4.15.0-29-generic #31~16.04.1-Ubuntu SMP Wed Jul 18 08:54:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux 与相机配合正常。
4.15.0-45-generic #48-Ubuntu SMP Tue Jan 29 16:28:13 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux 没有。

如何继续在 Ubuntu 18.04 上使用我的相机？有什么建议吗？操作系统将我的相机确定为Bus 002 Device 004: ID 0ac8:307b Z-Star Microelectronics Corp. USB 1.1 Webcam 我的相机是Canyon CNR-WCAM43G

有可能开发人员没有将旧驱动程序包含在新内核版本中，我不知道为什么。Skype 和 Cheese 也看不到摄像头。我尝试了命令cheese和cheese /dev/video0

答案1

经过一番搜索，我在 lauchpad 上发现了这个错误https://bugs.launchpad.net/ubuntu/+source/linux/+bug/144745

建议的解决方案是卸载 2 个模块并重新加载

sudo modprobe -r gspca
sudo modprobe -r zc0301
sudo modprobe gspca

一个永久的解决方案是将zc0301/etc/modprobe.d/blacklist-zc0301.conf模块。创建包含此内容的文件

blacklist zc0301

尝试关闭安全启动。对于我的戴尔笔记本电脑，我在启动时按住 F2 进入 BIOS。然后寻找禁用安全启动的选项。
