Bug Report: Intel IPU6 Camera Regression on XPS 9320 (Mint 22/Noble Base) #128
Description
The Intel MIPI camera (IPU6) on the Dell XPS 13 Plus 9320 is no longer functional out-of-the-box. While it worked in previous Mint versions (Victoria/Vanessa), the current implementation of v4l2-relayd fails to initialize the pipeline.
Hardware Information:
Device: Dell XPS 13 Plus 9320
Camera Sensor: Intel IPU6 (ov01a10)
OS: Linux Mint 22 (Cinnamon) / Ubuntu 24.04 (Noble) base.
Steps to reproduce:
Open any camera application (Cheese, Brave, Zoom).
The camera is either not detected or shows a black screen.
Checking systemctl status v4l2-relayd reveals GStreamer assertion failures.
Technical Logs & Findings:
Service Failure: v4l2-relayd returns several GStreamer-CRITICAL errors:
gst_pipeline_use_clock: assertion 'GST_IS_PIPELINE (pipeline)' failed
Permission Regression: The Intel hardware nodes (/dev/video* and /dev/media*) do not have the correct permissions for the standard video group.
PSYS Access: Even when permissions are set to 666, the CamHAL returns:
[CamHAL[ERR] Failed to open PSYS, error: Permission denied]
This indicates the process requires elevated privileges or a specific udev rule that is currently missing in the Mint/Noble build.
Known Working Workaround:
The camera hardware is functional, but only when manually bridged via GStreamer with root privileges using this specific pipeline:
sudo gst-launch-1.0 icamerasrc ! video/x-raw,format=NV12,width=1280,height=720 ! v4l2sink device=/dev/video0
Expected Behavior:
The v4l2-relayd service should automatically negotiate this pipeline and permissions at startup, as it did in previous versions.
