try different kernel, for example: linux 5.15.32-1
but shouldn’t I keep updating my kernel?
In my system, I have:
Currently running: 5.17.1-3-MANJARO (linux517)
The following kernels are installed in your system:
- linux419
- linux510
- linux514
- linux515
- linux516
- linux517
- linux54
why the hell do you have so many kernels installed haha… uninstall the following: linux419, linux514(its EOL), linux54… and boot into your 5.15 and check if your webcam works…
If you reload the uvcvideo again, does it makes a difference?
sudo rmmod uvcvideo
sudo modprobe uvcvideo
I have the same issue with 5.15 but in 5.10, works fine
hi, I ran these 2 commands,
Unfortunately they don’t make a difference
Is there any other solution apart from booting into an older kernel?
I removed 419, 54 and 514 as you suggested.
I also tried booting into 510 and 515, still no luck.
Camera is not being detected in the previous kernel versions as well now 
Is not the first time that webcam support just disappeared. 
After a few reboots it was fixed in 5.15
I must have booted with 5.15 about 4-7 times now… still no change
is there no actual fix in the latest kernel?
maybe try booting into an really old kernel, for example the 4.19 and see… if it still doesnt work, try booting for example into linux mint live usb, and check if it works there, to see if its only an arch issue or a linux issue
how to go about getting a linux mint live usb?
download linux mint iso from here and use Ventoy to flash it on USB, then boot from the usb into Mints live session and check
thank you!
will try this
meanwhile, I’d really appreciate it if anyone can suggest more directions to actually fix the issue 
and what is the exact name/model of your webcam?
I have not been able to find the exact model of my webcam.
This is my laptop though :

ran a few commands again:
Still no fix here 
@brahma @bogdancovaciu sometimes in between the camera would randomly work, but most times it goes undetected.
Even after my latest kernel update
You can use most competible webcam for Windows 11 laptops to avoid issues like this.
My laptop is the “Acer Predator”
It came with built-in Windows 11, before I changed it to Manjaro Linux.
I’m assuming the laptop’s webcam was by default compatible for Windows 11.
