（我被邀请这里提出这个问题是一个新问题）
我有一台运行 Ubuntu 23.04 的戴尔 Latitude 7640 笔记本电脑（2023）。
无法识别集成网络摄像头，但外置摄像头工作正常。制造商将集成摄像头描述为“FHD/IR 摄像头，配备 ExpressSign-In + 智能隐私、时间降噪、摄像头快门、麦克风”，在 Windows 上运行良好（我的机器上不再安装 Windows）。
在没有插入外部网络摄像头的情况下，询问
sudo lshw -C video

和
ls -l /dev/vid*;id
返回

插入外部网络摄像头后，lsusb我得到了

已发布解决方案这里适用于运行 22.04 的 Dell 7340 / 7440 上的网络摄像头。此解决方案也适用于我，因此我将其重现以便于参考。
安装IPU6/IPU6EP手动堆叠：
sudo add-apt-repository ppa:oem-solutions-group/intel-ipu6
sudo apt install linux-modules-ipu6-generic-hwe-22.04 linux-modules-ivsc-generic-hwe-22.04
sudo apt install libcamhal-ipu6ep0
sudo reboot
如果此操作未自动完成，请将视频组添加到您的用户。
您的集成网络摄像头现在应该可以在 Zoom、Skype 和 OBS 上运行，但不一定可以在 Cheese 上运行。
