apport information
** Tags added: apport-collected
** Description changed:
Hardware: Dell Latitude 7440, Intel Raptor Lake IPU6 [8086:a75d], sensor
OmniVision OV02C10 (ACPI OVTI02C1:00)
System: Ubuntu 26.04.1 LTS, kernel 7.0.0-1015-oem, libcamera 0.7.0-1ubuntu2,
PipeWire 1.6.2
Summary:
The integrated camera is detected and streams, the white LED turns on, but
every frame is black.
The same camera works correctly under Windows on this machine, and the
privacy shutter is open
(lens visibly uncovered).
What works:
- intel-ipu6 loads, firmware authenticates, "Found supported sensor
OVTI02C1:00", "Connected 1 cameras"
- libcamera lists the camera (simple pipeline handler, software ISP)
- PipeWire exposes it as "ov02c10 [libcamera]"
What fails:
- gst-launch-1.0 libcamerasrc ! videoconvert ! autovideosink -> window
opens, image fully black
- Same result with LIBCAMERA_SOFTISP_MODE=cpu (so not the GPU debayer path)
- Soft ISP AGC debug shows exposure pinned at maximum (2320) and gain
increasing, while almost all
pixels stay in the lowest histogram bin (~128700 of ~131000), even when
pointing at a bright light
Kernel messages while streaming:

libcamera messages:
'ov02c10 15-0036': Unable to get rectangle 0/1/2 on pad 0/0: Inappropriate
ioctl for device

IPASoft: Failed to create camera sensor helper for ov02c10
Also tested:
- Kernel 7.0.0-38-generic with linux-main-modules-ipu6-7.0.0-38-generic: same
black image
-
/sys/bus/wmi/devices/6932965F-1671-4CEB-B988-D3AB0A901919/dell_privacy_supported_type
reports
"[Camera Shutter] [unsupported]", so no Dell hardware privacy mute is
involved
- The Intel HAL stack (libcamhal / icamerasrc) is not available in the 26.04
archive, so it could not be tested

(Dell Inspiron 7440, same "LED on, black image" symptom on 26.04)
Expected: a visible image from the integrated camera.
