There is no physical button for the camera. Still I have tried Fn+ F1 to F12 with no avail.

Masters, please help.

Hi anyone it would be great if you get a time to help me. If the information is not enough or not in proper format please let me know.

ewaller · 2024-12-31 18:27:28

You assert that lsusb does not report the camera. Could you post that output? Which Acer model is it? Do you dual boot Windows?

Also, when posting, please use BBCode code tags around program output and file contents. That link is also under every message post box.

Thank you ewaller for your kind response.

Yes I have installed the arch on external ssd. I have windows11 installed on internal ssd. the camera is working fine with windows11.

ewaller · 2024-12-31 22:57:38

Well, nothing there looks like a webcam.
This mint thread indicates you are not alone: https://forums.linuxmint.com/viewtopic.php?t=431249

Does windows see this as a USB device? I wonder if the system is hiding it from you.

Piyush · 2025-01-01 16:13:14

Yes I went through that forum and some others. But some of them had the camera working before even though lsusb did not show the camera.
I don't know how to check if windows11 is seeing this as a USB device. On device manger under usb its not showing (also, the fingerprint sensor is not showing, they have different catagories). the camera has different catagory there.

Do you happen to have /dev/video1 ?
What if

$ ffplay /dev/video1

?

Maybe it's not a USB camera?

This is not a USB camera, it is connected directly to image processing unit (IPU) on PCI bus.

Did it work before and just stopped, or it has never worked?

I i could not find any driver for that in intel-ipu6-drivers, i tried loading all the driver with modprobe.
