webcam not working on XPS 9320 with Ubuntu 22.04.3

[Davide Scarso]

Hi,

I installed Ubuntu 22.04.3 on XPS 9320 (came with Windows pre-installed). Both "HAL library for MIPI Camera through Intel IPU6 by libcamhal0" and "hardware support for Dell XPS 13 9320 by oem-somerville-tentacool-meta" were automatically activated after install. Webcam however was not detected

I saw bugs #2039471 and #2039746, and followed what's suggested there but to no avail. Camera is detected now but gives a black image (0 FPS).

Could you upload apport log by $ sudo -E oem-getlogs

Thanks,

[Davide Scarso (ds451)]

Here's the logs, your help is much appreciated.

[Kai-Chuan Hsieh (kchsieh)]

Hello,

I find your ljca driver for the usb bridge is not probed [1]. Could you check if you have the latest firmware installed [2], Intel 2D Imaging/MCU/Visual Sensing Controller Driver for Camera?

It won't provide USB bridge firmware info. Please boot into Windows to check or consult dell support for it. If you can remove Windows, you can consult Dell to get Ubuntu preload image to have a try.

[Davide Scarso (ds451)]

Ok, I will do that and maybe report back. Thanks for your support.

[Davide Scarso (ds451)]

I upgraded the webcam firmware in Windows as you suggested and did a fresh install of Ubuntu 22.04.3. Again, both "HAL library for MIPI Camera through Intel IPU6 by libcamhal0" and "hardware support for Dell XPS 13 9320 by oem-somerville-tentacool-meta" were automatically activated after install. Webcam however did not work.

libcamhal-ipu6ep0 was already installed, but linux-modules-ipu6-generic-hwe-22.04 and linux-modules-ivsc-generic-hwe-22.04 were not.

Then I manually installed linux-modules-ipu6-generic-hwe-22.04 and linux-modules-ivsc-generic-hwe-22.04 and the webcam is now working.

I confirm that Cheese also work if launched with sudo cheese -d "Intel MIPI Camera".

Thank you again for your help!

[Kai-Chuan Hsieh (kchsieh)]

I was surprised the modules aren't installed with libcamhal-ipu6ep0, since they are recommened with libcamhal-ipu6ep0 [1]. Can you have linux-modules-{ipu6,ivsc}-gwneric-hwe-22.04 installed through
$ sudo apt update
$ sudo apt dist-upgrade
after fresh install?

[1] http://dell.archive.canonical.com/dists/jammy-somerville-tentacool/public/binary-amd64/Packages

[Davide Scarso (ds451)]

I did the whole process once again, to confirm:

1) A fresh installation of Ubuntu 22.04.3. "HAL library for MIPI Camera through Intel IPU6 by libcamhal0" and "hardware support for Dell XPS 13 9320 by oem-somerville-tentacool-meta" are automatically activated during install. Webcam does not work.

2) The system however immediately suggests several updates, through the Update GUI. Did the update and rebooted.

3) After reboot, sudo apt update; sudo apt dist-upgrade says everything is already updated. sudo apt install libcamhal-ipu6ep0 says the most recent version is already installed. linux-modules-ipu6-generic-hwe-22.04 and linux-modules-ivsc-generic-hwe-22.04 are not installed (see first logs file in attached zip archive). Webcam does not work.

4) sudo apt install linux-modules-ipu6-generic-hwe-22.04 and linux-modules-ivsc-generic-hwe-22.04. After reboot webcam works as expected (see second logs file).

[Davide Scarso (ds451)]

(btw, I noticed a typo in the Description of libcamhal-ipu6ep0:

"Tansitional package for libcamhal0 This is a transitional package for libcamhal0, and can be safely removed after the installation is complete."

The first "transitional" is missing the "r" after the "T").

[Shih-Yuan Lee (fourdollars)]

I made https://code.launchpad.net/~fourdollars/ipu6-camera-hal/+git/packaging/+merge/457381 to fix the typo. Thx.

[Cyrus Lien (cyruslien)]

I confirmed the issue by steps 1~3 in #9. Users have to manually install ipu6 and ivsc drivers to make the webcam work.

Which is an online install and ubiquity was try to upgrade it as:
def install_extras()
...cache.update(sources_list=target_sources_list)

[jeremyszu (os369510)]

So here are total three topics in the installer/images:

1. linux-modules-ipu6/ivsc (and future usbio) are not in image (CDROM) and def install_extras() only install packages from CDROM even if users perform online installation.

2. installer needs an extra `ubunut-drivers list` to detect if any packages (With modaliase) from oem archive are required for this platform. A potential fix: https://git.launchpad.net/~os369510/ubiquity/commit/?id=ff333f4013ecbc6fe662bca4ff8d7f2657497473, which could solve the potential bug report (i.e. my wireless doesn't work, because it needs backport-iwlwifi-helper from oem-archve) in the future.

3. apt install ${oem-meta} (when upgrading it from def install_extras()) will fail if "XB-Ubuntu-OEM-Kernel-Flavour" points to "oem" because only linux-oem-22.04 in the CDROM (iso) but the real oem meta packages require linux-oem-22.04{d,+} but linux-oem-22.04 points to "linux-oem-22.04c".
I'm wondering if we can get updates from ubuntu-archive in def install_extras().
