Built-in webcam not working on Acer Nitro laptop, also broken on Ubuntu

System details

System details - Device: Acer Nitro laptop - GPU: NVIDIA GeForce RTX 5050 Laptop GPU - OS tested: - Omarchy: camera not detected / not working - Ubuntu: camera also not detected / not working - Kernel tested on Ubuntu: 7.0.0-22-generic - Display/session: GNOME / Linux desktop - Camera type: built-in laptop webcam - External USB webcam: not tested / unknown

What's wrong?

What's wrong?

The built-in laptop camera does not work on Omarchy. I also tested the same laptop on Ubuntu and the camera does not work there either, so this may not be an Omarchy-specific configuration issue.

The camera is not detected by normal webcam apps, and it appears that the built-in webcam may not be exposed as a standard USB/UVC camera. This laptop likely uses a newer MIPI/CSI/ISP camera pipeline, which may require additional kernel driver, firmware, or libcamera/media-controller support.

Expected behavior:

• Built-in camera should appear as a usable webcam.
• Camera should work in browser/web apps, Cheese, OBS, or other camera apps.
• A /dev/video* device should be available if the camera is supported.

Actual behavior:

• Built-in camera does not work.
• Camera apps do not show a usable webcam.
• Same issue happens on Ubuntu, so the issue may be missing upstream Linux hardware support for this laptop camera.

Could Omarchy document whether this laptop camera is unsupported upstream, or include any required packages/firmware/libcamera configuration if support exists?

Note: I am reporting this to Omarchy because I tested Omarchy and the camera did not work, but the same camera also fails on Ubuntu. So I understand this may be an upstream kernel/firmware/libcamera support issue rather than a direct Omarchy bug.

I think this is our reach to correct. This is something that has to be fixed upstream in the kernel or by Acer supplying a driver.

Target Hardware: Acer Nitro 16S AI (AN16S-61-R0Z7), AMD Krackan APU platform (Zen architecture), NVIDIA RTX 5060 Mobile.

Operating System: Arch-based Linux (Kernel 7.1.9-arch1-2) using Omarchy.
Boot Environment: Limine bootloader loading a Unified Kernel Image (UKI).

Hardware Architecture: Integrated Sunplus USB Camera (VID 0408:PID 4059) and Digital MEMS Microphone array located on a unified top-bezel PCB, sharing a common switched +3.3V power rail via an eDP cable harness.

The shared +3.3V power plane is hard-gated by the Acer Embedded Controller (EC). Under Linux, the EC holds the GPIO power-enable pin LOW because it does not receive proprietary ACPI/WMI initialization signals. The digital MEMS microphone array and Sunplus camera share the same physical 3.3V power rail. Any failure by the EC to power the camera disables the microphone array simultaneously.
Enabling the hardware requires either a custom kernel patch mapping the Krackan EC RAM power registers or a upstream driver update for amd-pmf / acer-wmi.

PS: Have been trying to apply a custom kernel patch since the day I booted linux, still nothing.

the problem found and fixed pls refer to my github repo https://github.com/abduvaliy-engineer/acer-nitro-anv16s-camera-fix

[abduvaliy-engineer]

Understood. Since the camera also fails on Ubuntu and does not expose a usable /dev/video* device, this appears to be missing upstream kernel/firmware support or an Acer driver issue rather than an Omarchy bug. I will continue tracking it through Acer and upstream Linux camera support. Thanks for confirming.

Thanks a lot, it did fix the camera and microphone issue on my machine.
