** Description changed: - Dell Pro 16 Plus PB16250 - Ubuntu 24.04.3 LTS - linux-oem-24.04 (6.14.0-1018-oem) + Ubuntu complies v42loopback-dkms/questing into derived and generic 6.17 + kernels. That is linux/questing, linux-oem-6.17/noble and linux- + hwe-6.17/noble, etc. have v4l2loopback.ko built from v4l2loopback- + dkms=0.15.0-0ubuntu2. - The internal camera is not detected. - All Intel IPU6 kernel modules (intel_ipu6, isys, psys) and - multiple sensor drivers load successfully, but no - /dev/media* or /dev/video* devices are created. + With v4l2loopback upstream commit 5092ea9 + (https://github.com/v4l2loopback/v4l2loopback/commit/5092ea9a7667564fbfc7e4e4ae9d8a2b2757649f), or v4l2loopback >= v0.14.0, it breaks gstreamer/noble, but works fine with gstreamer/questing and gstreamer/resolute. - BIOS updated to 2.8.1. - Secure Boot disabled. + Therefore for linux-oem-6.17 kernels (linux-oem-6.14 is not affected), + v4l2-relayd dies again and again until disabled by systemd, and camera + access from browser will then fail. - This looks like missing INT3472 / ACPI sensor enablement - for this specific Dell model. + ================================== ProblemType: Bug DistroRelease: Ubuntu 24.04 Package: linux-image-6.14.0-1018-oem 6.14.0-1018.18 ProcVersionSignature: Ubuntu 6.14.0-1018.18-oem 6.14.11 Uname: Linux 6.14.0-1018-oem x86_64 NonfreeKernelModules: zfs ApportVersion: 2.28.1-0ubuntu3.8 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC0: willedi 3549 F.... pipewire - willedi 3556 F.... wireplumber - /dev/snd/seq: willedi 3549 F.... pipewire + USER PID ACCESS COMMAND + /dev/snd/controlC0: willedi 3549 F.... pipewire + willedi 3556 F.... wireplumber + /dev/snd/seq: willedi 3549 F.... pipewire CasperMD5CheckResult: pass CurrentDesktop: MATE Date: Wed Dec 17 20:44:14 2025 InstallationDate: Installed on 2025-12-15 (2 days ago) InstallationMedia: Ubuntu-MATE 24.04.3 LTS "Noble Numbat" - Release amd64 (20250805.1) IwConfig: - lo no wireless extensions. - - enx4086cbb4dd85 no wireless extensions. - - wlp0s20f3 no wireless extensions. + lo no wireless extensions. + + enx4086cbb4dd85 no wireless extensions. + + wlp0s20f3 no wireless extensions.
