我刚刚在新的 X1 Carbon 上安装了 Ubuntu 22.04第 11 代一切似乎都正常，除了 MIPI 网络摄像头（这并不令人意外）。这个问题解决了同样的问题，但针对的是 X1 Carbon第 10 代。我遵循了以下解决方案中概述的所有说明，特别是使用 dkms，并且只要有选择，我总会选择 ipu6ep。
这几乎可以正常工作。在命令之后
sudo -E gst-launch-1.0 icamerasrc buffer-count=7 device-name=ov2740-uf ! video/x-raw,format=NV12,width=1280,height=720 ! v4l2sink device=${DEVICE}
摄像头灯亮起，表示某物正在发生。但是在终端上我看到以下输出：

最后几行每半秒左右重复一次，相机灯一直亮着。然而 cheese 无法检测到相机。我还尝试使用以下命令启动 cheese
cheese -d "Intel MIPI Camera"
但这没有帮助。
有没有人遇到过类似的情况并且能让 MIPI 相机正常工作？
答案1
https://wiki.ubuntu.com/Lenovo有一些有关英特尔 MIPI 相机的说明，您可以尝试一下。
Cheese 存在一个已知问题，即它无法通过 v4l2loopback 解决方法支持英特尔 MIPI 摄像头。
最好使用 Google Chrome 或 Mozilla Firefox 访问https://webcamtests.com/检查你的 MIPI 相机。
