Doesn't work on ThinkPad X1 Carbon Gen 10 with Ubuntu 24.04

[80kk]

I have Lenovo ThinkPad X1 Carbon Gen 10 with Ubuntu 24.04LTS and 6.8.0-38-generic stock kernel installed. Using apt I've installed intel-usbio-dkms and then all four repositories as mentioned on https://github.com/intel/ipu6-drivers?tab=readme-ov-file For ipu6-drivers I decided to use DKMS method, it built and loaded without any issues:

# dkms status

usbio-drivers/0~git202312141918.78ffb706-0ubuntu2, 6.8.0-38-generic, x86_64: installed

I've also tried Intel Integrated Image Processing Unit 6 driver from Additional drivers but it didn't make any difference except ipu6-drivers module didn't build because it was already provided.

What else I can do to narrow down the issue?

Was just able to get it working on PopOs under kernel 6.9.3-76060903-generic. Also installed through dkms. Do you get any output when running this?

sudo gst-launch-1.0 icamerasrc ! autovideosink

Will hopefully make a more detailed tutorial on the specific setup i got it working under.

Same situation.
Lenovo X1 Carbon G10 with MIPI camera
6.8.0-45-generic
Upgraded today to Ubuntu 24.04.1 LTS

Running "sudo gst-launch-1.0 icamerasrc ! autovideosink"
I get:

[alesrebec]

I just found this 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}

If I run it my camera status light turns on.
I then visited this web cam test page https://webcamtests.com/check and the camera is working!

I am guessing gstreamer can#t see this plugin but I can't find how to fix it.

no luck here.

@80kk
I also get this error if I run it again now but it works if it's placed in a script like this:

#!/bin/bash

DEVICE=/dev/video0

# Set the path to the GStreamer plugins
export GST_PLUGIN_PATH=/usr/lib/gstreamer-1.0:/usr/local/lib/gstreamer-1.0

# Run camera command
gst-launch-1.0 icamerasrc buffer-count=7 device-name=ov2740-uf ! video/x-raw,format=NV12,width=1280,height=720 ! v4l2sink device=${DEVICE}

Name it "run_camera.sh", make it executable:

chmod +x run_camera.sh

and then run it as sudo:

sudo ./run_camera.sh

I don't have v4l2sink module but I can't see it is required? However setting a path gives me:

For running that command it's required to have v4l2sink. It takes the video data and outputs it to a device compatible with Video4Linux (V4L2)
Try installing it and maybe adjusting the command to eventually make it work. (maybe different device-name, video format, etc..)
