Using the webcam on zbook ultra g1a, Linux (ubuntu 25.04)

[Lieall]

hello.

I have purchased and am using a laptop (zbook ultra G1A).

Of course, the default OS for that laptop is Windows 11, and I know that everything works fine on Windows 11.

My job requires me to use Linux quite a bit in addition to Windows, so I installed Linux via dual boot.

However, recently, after installing Linux, I was checking the status of my devices and noticed that my webcam was not working.

Is it installed correctly, or is there a Linux distribution or version that is optimized for this HP laptop, and if so, is there a driver or software installation that might fix the problem? I'll leave the product and Linux version information I'm using below.

- Laptop: HP ZBOOK ULTRA G1A (AMD RYZEN AI MAX 395+, 64GB)
- Linux distribution: Ubuntu 25.04
- Kernel: 6.14.3 (latest)

Hi,

the camera in your g1a is not a normal usb camera, it uses isp for better performance. You can find open source drivers here:

https://github.com/amd/Linux_ISP_Kernel/tree/4.0

https://github.com/amd/Linux_ISP_libcamera/tree/3.0

But installation is not trivial, lets hope that the kernel driver gets mainstreamed into the kernel and userspace tools get adopted in one of the next Ubuntu releases.

The g1a is only certified on Ubuntu 24.04. LTS with Ubuntu OEM Kernel, but i dont think certification covers the camera.
