I have just installed Ubuntu 22.04 on my new X1 Carbon Gen 11. Everything seems to be working, except, unsurprisingly, the MIPI webcam. This question addresses the same issue but for the X1 Carbon Gen 10. I followed all the instructions outlined in the solution below, specifically using dkms and also always went with the ipu6ep wherever I had a choice.
This almost works. After the command
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}
the camera light switches on, indicating that something is happening. However on the terminal I see the following output:

The last couple of lines are repeated every half second or so and the camera light stays on. However cheese is not able to detect the camera. I also tried to launch cheese with the command
cheese -d "Intel MIPI Camera"
and this does not help.
Is there anybody in a similar situation and got the MIPI Camera to work?
