Public bug reported: 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: intel_ipu6_isys.isys intel_ipu6.isys.40: csi2-1 error: Frame sync error intel_ipu6_isys.isys intel_ipu6.isys.40: csi2-1 error: Transfer FIFO overflow intel_ipu6_isys.isys intel_ipu6.isys.40: csi2-1 error: Inter-frame long packet discarded intel_ipu6_isys.isys intel_ipu6.isys.40: csi2-1 error: Inter-frame short packet discarded int3472-discrete INT3472:06: GPIO type 0x02 unknown; the sensor may not work libcamera messages: 'ov02c10 15-0036': Unable to get rectangle 0/1/2 on pad 0/0: Inappropriate ioctl for device 'ov02c10 15-0036': The sensor kernel driver needs to be fixed 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 Possibly related: https://discourse.ubuntu.com/t/ubuntustudio-26-04-mipi-ipu6-camera-not-working/87859 (Dell Inspiron 7440, same "LED on, black image" symptom on 26.04) Expected: a visible image from the integrated camera.
