How to use the IPU6 webcam with kernel 6.10+?

I could not find my laptops' camera sensor - does anyone has any tips? It's DELL PB14250

Thank you dmoebius for post https://bbs.archlinux.org/viewtopic.php … 0#p2213350.
(In particular highlighting on obtaining missing driver for sensors that are already supported by the kernel).

My ov02c10 camera (sensor: OVTI02C1) for laptop Dell Latitude 9330 (kernel version: 6.15.9) is now fully functional on Arch.

(The fastest and most rewarding setup I ever had to get this camera working on various Linux systems over 3 yrs Special thanks for that )

Thank you, that seems to work for me too, but signal does not see it ... Is there anything still to be configured?

Moreover since I spotted that the intel-ivsc-firmware is proprietary, not maintained anymore and apparently not necessary, I've removed it from the dependencies of intel-ipu6-dkms-git. I've also ficed the license fierld.

This is the PKGBUILD

    printf "r%s.%s" "$(git rev-list --count HEAD)" "$(git rev-parse --short HEAD)"
}

prepare() {
    cd "$srcdir/$_pkgname"
    sed -i "s/^PACKAGE_VERSION=\".*\"$/PACKAGE_VERSION=\"$pkgver\"/g" ./dkms.conf
}

package() {
    cd "$srcdir"
    install -dm755 "$pkgdir/usr/src"
    cp -rT "$_pkgname" "$pkgdir/usr/src/$_pkgname-$pkgver"
}

this is the output of executing namcap intel-ipu6-dkms-git-r236.9bff73689-1-any.pkg.tar.zst

Having the same problem with the OVTI08F4 sensor.

it detects the sensor, but it wont show up in the camera settings. this is a Dell Inc. Dell Pro Max 16 Premium MA16250 . Any idea if this can be made to run? Tried everything I found on the net and in this thread nothing worked until now.

I am not having much luck getting my camera to work on my Latitude 7350 Detachable on kernel 6.16.1
cheese does not work, camera not picked up by zen-browser either, it shows a list of like 30 devices but none of them work.

dmesg shows

[    3.250401] intel-ipu6 0000:00:05.0: enabling device (0000 -> 0002)

So it looks like at least the camera is detected

I have not seen anyone else running arch on a 7350 detachable, but if anyone *is*, and you somehow got the front camera working, some tips would be appreciated

With the very latest kernel I do not need anymore air packages, but:
1) the camera is upside down in scam
~~2) signal still doesn't see it~~ [Workaround] Signal-desktop see the camera if started using libcamerify signal-desktop
3) the boot process is longer (it stops 10 secs in the rfkill part)
4) I often get kernel crash back trace at shutdown

Is anyone spotting similar issues?

May need some help on getting this to work properly

I have an XPS 9320 (i7, 1260P) with an ov01a10, which is supported.

I managed to get the webcam to work by installing intel-ivsc-firmware. After doing this, I can use it in stuff like cheese, gstreamer (with libcamerasrc), firefox with pipewire, ...

Now, the issues start. first, the camera image appears cut on the sides (cropped) in everything outside of cheese. Also, the OBS source for pipewire is quite broken, but that is to be expected I guess as it says "BETA".

The bigger issues, however, are some issues like the image sometimes stuttering (sometimes when I move away from the webcam, in some programs) and the image appearing dithered (made out of pretty big RGB chunks, which flicker) and with a strong greenish tint. None of this happened while I was still using this repo in pre-6.10 kernels. everything worked fine back then.

Also, I'm having some trouble setting up a v4l2 camera with v4l2-relayd. I tried following the steps in https://github.com/henkv1/ov08x40_arch (sort of, as my sensor has a kernel driver), by doing the following, but I'm still only getting a black image from the v4l2loopback "Virtual Camera"

# dkms add usbio-drivers/
#  dkms autoinstall
$ cd v4l2-relayd
$ makepkg -si
# systemctl enable v4l2-relayd
# echo -e "gpio-usbio\ni2c-usbio\nv4l2loopback" | sudo tee -a /etc/modules-load.d/ov01a10.conf
$ reboot

Some other hopefully useful outputs:

Yeah also, any way to get rid of all those ipu6 devices? they show up in obs and telegram but not other stuff that uses v4l2, like discord

I just noticed, the webcam stops working after hibernation. Likely related to me having to unload i2c_ljca (as the laptop freezes immediately after waking up if I don't) and reload it again after. I found this https://github.com/intel/ivsc-driver/issues/49

Thanks a lot in advance for any tips or fixes

I am having all of these same issues. Did you find a solution for any of them yet? On `linux 6.16.3.arch1-1` (XPS 9320 / Dell XPS 13 plus)

Thank you dmoebius for post https://bbs.archlinux.org/viewtopic.php … 0#p2213350.
(In particular highlighting on obtaining missing driver for sensors that are already supported by the kernel).
My ov02c10 camera (sensor: OVTI02C1) for laptop Dell Latitude 9330 (kernel version: 6.15.9) is now fully functional on Arch.
(The fastest and most rewarding setup I ever had to get this camera working on various Linux systems over 3 yrs Special thanks for that )

I also have ov02c10 (on Latitude 7440 2-in-1), and this doesn't seem to work for me. `cam -l` indeed detects the camera:

I have ivsc-firmware and intel-ipu6-dkms-git installed, kernel 6.12.45-1-lts (I get an oops from the dkms module on the current non-lts kernel)

(edit: the same issue occurs with 6.16.4-arch1-1 kernel after uninstalling the dkms package: the ov02c10 driver has recently been upstremed)

The camera is identified by v4l2-ctl, but not by cam -l
Nope. According to Hans De Goede our sensor is not supported yet https://hansdegoede.dreamwidth.org/28841.html

Is there any update I cannot find regarding this?

gaelic · 2025-10-30 08:40:50

So the wait should be over, the IPU6 and IPU7 drivers have been merged with 6.17, 6.18 will bring the missing USBIO parts: https://www.phoronix.com/news/Linux-6.18-USB

I guess from that moment most cameras should work out of the box, without additional packages needed (?)

Today the webcam (that is still upside down) has started flashing at roughly 1Hz.

Next time I'll change my laptop I'll probably stay away from Intel and Dell

I have the very same issue for months, hoping that it would be fixed after each kernel upgrade...
It seems that if I refocus the camera with my hand I can stop it for some time :-/
I think I remember reading a libcamera bug that could be related, but I was not able to find it again: I'll try again !

[edit] It is not this one, but the flickering issue is mentioned: https://bugzilla.redhat.com/show_bug.cgi?id=2355032

I actually just installed libcamera-git (r5901.3a835ff4-1) from AUR and it seems to work now... Let's hope that it is really the case ! (because it seems that the flashing issue might be triggered by the light condition in the room)

The camera is still inverted, but the flickering seems to stop after about 10 seconds. The image quality is really bad tho. Surprisingly, the camera is recognized on chromium and webcam test displays the inverted video feed. I'm on 6.17.9.

gaelic · 2025-12-05 09:50:48

Even with linux 6.18 I have problems to get the camera running on my Thinkpad X1 Carbon gen12.
Good things first: the camera is now detected and I can also choose in qcam or also firefox.
Bad things: the camera "activates", but "crashes" and I never get a picture or stream, in gnome the "attention, camera is running indicator" stays on after that. Also the laptop (especially firefox) starts having problems, with small freezes getting worse and worse. So far i have this in dmesg:
