Latitude detachable laptop...webcams not working
Hi guys!
So...I bought a Latitude 7350 detachable laptop, as a replacement for a Surface where the cams don't work on Linux. This laptop seemed rather powerful and compatible, while still keeping the weight constrained (something the Minisforum V3 isn't as successful in). Also,
I prefer the rear being a stand thingy like on the Surface, and not some detachable flap you need to turn about 150 degrees to turn it into a mandatory stand (because when closed...it blocks the intake fans).
Anyway...Seems that while the camera module IPU6 is meant to be supported on Linux...I don't seem to be able to get any image. Any ideas what I might be doing wrong?
I installed KDE Neon (I'd prefer a KDE-based distro) and installed intel-ipu6-dkms and intel-usbio-dkms. But the camera doesn't seem to work. Any ideas how could I troubleshoot this?

intel-ipu6 0000:00:05.0: Direct firmware load for intel/ipu6epmtl_fw.bin failed with error -2
This has led me here, but after installing a bunch of modules from the additional repo...I'm still getting not much at all.

It looks like a bunch of unhappy Windows users have also been having trouble with that particular laptop and camera, from a quick search, so I don't know how solid the driver work is for that particular camera:

Could be that the development is underfunded or other problems are going on. Intel had a huge number of layoffs recently.
I don't have familiarity with that camera, but I will suggest a fallback plan if you don't get it ironed out: grab yourself a clip-on USB webcam.

Run a scan to share what does and doesn't work on your machine so that others can see. Don't worry about it. This is a good thing for everyone and not some exploit. Check if others have scanned with the same hardware. Look at what kernel they are running and if it has the same problem or notes. You may see the hardware label and find other machines with the same that may or may not be working.

in reply to iturnedintoanewt • • •The important part is the hardware id of the camera, you have to search for this, drivers and kernel modules use this number to check if they are needed:

I found a documented laptop with this camera: wiki.archlinux.org/title/Dell_…
They link to some patches there, it may work with that
As I see the date of the patch is this year March, I guess simply the laptop is too new. If you don't want to fiddle, just switch to some rolling release distro, and the patches will be merged upstream soon. After a kernel update your camera will magically start working. This would be the easiest solution if you can live some more months without the camera.
