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:

Setting pipeline to PAUSED ...

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?

  • I have been fighting the very same fight myself today (but on a Dell 5680). I just got it working. IPU6 seems to also need "ivsc". Checking my dmesg, I see many "intel vsc not ready", followed by "vsc_ace ... recv firmware id" just before "intel-ipu6-isys0: All sensor registration completed". (Hoping this is a clue for you, or anyone else ending up here) – Rawler Sep 04 '23 at 19:21

https://wiki.ubuntu.com/Lenovo has some instructions for Intel MIPI camera that you can try.

There is a known issue on Cheese that it can not support Intel MIPI camera via the v4l2loopback workaround.

It is better to use Google Chrome or Mozilla Firefox to visit https://webcamtests.com/ to check your MIPI camera.
