Comment 71 for bug 1955383

Hello,

I am having issues which look similar to those reported by Stuart in getting to run the Camera on a Lenovo X1 Gen10. (But unfortunately, rebooting did not help.) The camera shows up in gst-device-monitor as "ipu6" with unreasonable parameters, and gst-launch complains about 2:0:0:0 colorimetry.

This behavior is observed both in Ubuntu 22.04 with the default kernel 5.15.0-40 and in Ubuntu/Debian with a self-compiled kernel 5.18.9 with the ipu6/ivsc modules included (with small variations, the 5.18.9 does not manage to bring up the relayd, and no test device is present; and under 5.15, gst-device-monitor only reports the ipu6 device for root).

Any help is very much appreciated -- thank you! Let me know what other information to supply.

To start with, here's what I see for the default 5.15.0-40 kernel + ipu6 packages:
