Fixed Integrated Camera on Dell Latitude 7450 After Zorin OS 18 Upgrade

Hardware Support

Hi everyone,

I recently upgraded to Zorin OS 18, and my integrated camera stopped working. I managed to fix the issue myself and documented the full process. I also created a driver patch for the OV02E10 camera that I can share if needed.

My Configuration

  • Laptop: Dell Latitude 7450
  • OS: Zorin OS 18 Core (64-bit, Wayland)
  • Kernel: 6.17.0-1012-oem
  • CPU/GPU: Intel Core Ultra 7 165U / Intel MTL Graphics
  • RAM: 32 GB
  • Firmware: 1.13.0

Problem

After boot, the camera fails with:

ov02e10 i2c-OVTI02E1:00: failed to find sensor: -6

Root causes:

  1. Boot race condition: intel_skl_int3472_discrete probes before the LJCA GPIO chip is ready.
  2. Missing dvdd regulator: Stock ov02e10 driver only requests avdd, so sensor power fails.

Fix Overview

  1. Install build dependencies.
  2. Build and install usbio drivers for the Intel USB-IO bridge.
  3. Clone the ipu6-drivers repo.
  4. Patch the ov02e10 driver to add dvdd regulator support.
  5. Build and install the patched module.
  6. Blacklist modules to prevent auto-loading.
  7. Create a script to load modules in the correct order at boot.
  8. Create a systemd service for the script.
  9. Configure v4l2loopback for virtual video device.
  10. Configure v4l2-relayd to bridge the camera source to /dev/video0.
  11. Reboot and verify the camera works.

After the fix:

  • LED turns on only when the camera is in use.
  • No “failed to find sensor” errors.
  • Works with Chrome, GNOME Camera, and other apps.

I can share the .md guide and the driver patch if anyone wants to replicate this fix.

Hi and welcome.

Would be good if you wrote a separate thread in Tutorials & Guides section of the forum.

Welcome to the Forum!

Is there a Reason why You use an oem Kernel and not the default one?

I have the exact same model of laptop and am experiencing the same problem. Would you be willing to share your patch with me? Thanks!
