[SOLVED] Integrated Camera is not detected anymore

Hello everyone!

I have this really weird issue with my laptop and its integrated camera. I've discarded that this is a physical issue because someone else with exactly the same hardware had the same issue during the same date and the camera works normally from another OS (windows sadly). The camera was working with no issue until July 22 as you can see from the journalctl logs:

The next day the camera dissapeared from lsusb and there aren't any log entries related to the camera anymore. First I thought this was due to some updated package so I checked pacman's logs for that day

My only guess was that maybe the new kernel version broke something. So I decided to install linux-lts (5.10) but the camera is not detected there either.

I'm not sure how to proceed from here and I wanted to know if somebody knows how to debug this.

Thank you

Re: [SOLVED] Integrated Camera is not detected anymore

I'm having the same issue. No errors in any log, no entry in

lsusb

Camera is simply gone since July 21st for me. Logs show a boot cycle the 21st and another one the 23th in which the camera is no longer detected. I recon an upgrade broke something but I can't point to what exactly. Camera is enabled in the BIOS and my keyboard does not have a "deactivate camera/video" key.

Re: [SOLVED] Integrated Camera is not detected anymore

I was in contact with ombiez and they suggested that downgrading the kernel to 5.12 might work because 5.10 might not support the device either. We downloaded the 5.12.15 kernel and its headers and the camera works again (We checked both linux and linux-zen). So it seems this bug was in fact introduced by 5.13. Where should we report this?

Re: [SOLVED] Integrated Camera is not detected anymore

https://bugs.archlinux.org/task/71588#comment201369 suggest its will be fixed by https://git.kernel.org/pub/scm/linux/ke … ae59650a42 which is queued for 5.13.6 https://git.kernel.org/pub/scm/linux/ke … tate.patch
You can wait for 5.13.6 or build the kernel locally with that patch applied and see if it does fix the issue.

I built the kernel applying that patch and it solves the issue. Thanks for the help, I'm marking this as solved.
