自上次固件更新以来，我的集成网络摄像头（尽管已被检测到）一直显示黑屏。我尝试使用 Zoom 客户端、Google Meet 和 Slack huddle。所有情况都一样。
当我尝试启动它时，Cheese 没有响应（我不知道是否相关）。
我还尝试了网络摄像头测试https://webcamtests.com/，它说我的网络摄像头已被检测到，但测试显示黑屏。
是的，我的网络摄像头已在 BIOS 设置中启用。
v4l2-ctl --list-devices输出如下：
Intel MIPI Camera (platform:v4l2loopback-000):
/dev/video0
此文件 ( ) 的权限ls -l /dev/video0为：
crw-rw----+ 1 root video 81, 0 Apr 12 13:33 /dev/video0
是的，我的用户在该video组中。

我在网上没有找到有效的解决方案。我尝试将 BIOS 设置重置为默认设置，尝试重新安装gstreamer1.0-icamera，尝试重新安装v4l2-ctl。我的所有apt软件包都是最新的。我的所有快照都是最新的。
在此先感谢您的帮助！
答案1
我找到了一个可行的解决方案：
sudo add-apt-repository ppa:oem-solutions-engineers/oem-projects-meta
sudo apt install oem-somerville-tentacool-meta
sudo apt update
sudo apt full-upgrade
sudo systemctl poweroff
重新启动计算机它就可以正常工作了。
但是这个解决方案并不能解决Cheese问题。为了让它Cheese工作，我必须通过指定设备在终端中启动它：
sudo cheese -d "Intel MIPI Camera"
运行时"Intel MIPI Camera"与文件关联的设备在哪里/dev/video0v4l2-ctl --list-devices
