my Dell Precision 5470 webcam is not working on my Linux Mint 21.2 laptop. Some months ago it worked, but now, probably cause by some updates, it doesn't work. I tried some fixes that I found on internet (like this one described in this link https://wiki.ubuntu.com/Dell), but with no success. Here the fix that I tried:
$ sudo apt install oem-somerville-omastar-meta
$ sudo apt update
$ sudo apt full-upgrade
$ sudo systemctl poweroff
$ sudo add-apt-repository ppa:oem-solutions-group/intel-ipu6
$ sudo apt install linux-modules-ipu6-generic-hwe-22.04 linux-modules-ivsc-generic-hwe-22.04
$ sudo apt install libcamhal-ipu6ep0
$ sudo reboot
Output:
It doesn't work using Cheese:
dbortolu@db-laptop-unito:~$ sudo cheese -d "Intel MIPI Camera"
(cheese:6126): GLib-GObject-CRITICAL **: 21:21:47.363: g_value_dup_string: assertion 'G_VALUE_HOLDS_STRING (value)' failed
(cheese:6126): GLib-GObject-CRITICAL **: 21:21:47.363: g_value_dup_string: assertion 'G_VALUE_HOLDS_STRING (value)' failed
(cheese:6126): GLib-GObject-CRITICAL **: 21:21:47.363: g_value_dup_string: assertion 'G_VALUE_HOLDS_STRING (value)' failed
(cheese:6126): GLib-GObject-CRITICAL **: 21:21:47.363: g_value_dup_string: assertion 'G_VALUE_HOLDS_STRING (value)' failed
and using https://webcamtests.com/ the webcam is recognized but the webpage shows only black screen with this error message: The video track is paused. The webcam turns on the light for 1-2 seconds during the boot, but when it's used by some program still remains turn off and with no output.
Info:
I tried a lot of kernels (6.2.0-26-generic, 6.0.0-1017-generic, 6.1.0-1019-generic, 5.17.0-1035-generic, 5.19.0-50-generic) but all have the same problem. Secure boot is disabled and camera is enabled in bios.
Details:
Some useful outputs that might help.
