Intel MIPI camera not found

Support and Help

Glad to help!

Alright, keep an eye on that list in the next days, @roberto-derenzi

We have to give some time to the developers to fix all the issues, I guess.

Hey everyone,

I have been trying to fix mine for a few hours this time around but it looks like dkms cannot build for the latest kernel. Here is the root cause:

If anyone hears about the intel-ipu6-dkms module being patched, it would be great.

Hi @annalito,
a number of people successfully made the camera work by totally removing the intel-ipu6-dkms actually.

sudo apt-get remove --purge intel-ipu6-dkms
sudo apt-get autoclean 
sudo apt-get autoremove
sudo apt-get update
sudo apt-get upgrade
ubuntu-drivers list

There should be another driver listed that is not an oem-metapackage and not a dkms. If so, please install that one. Also, if you have installed libcamhal0, please purge it too.

I tried to apt remove also oem-somerville-treecko-meta and all ‘libcamhal’ libraries, besides `intel-ipu6-dkms’, and actually the output of

ubuntu-drivers list

changed (same oem-somerville-treecko-meta but different libcamhal-ipu6epmtl, same intel-ipu6-dkms. Still, after reinstalling these and checking

v4l2-ctl --list-devices

Intel MIPI Camera (platform:v4l2loopback-000):

/dev/video0

the result is a blank screen on

ffplay -f video4linux2 /dev/video0

Glad you solved, @annalito ! :partying_face:

Hi @roberto-derenzi,

so what did you reinstall? Only the oem metapackage and the libcamhal-ipu6epmtl ?

Please do NOT reinstall the dkms one (and if you did, please purge it).

Hi @feredicarike, thanks for your prompt reply! Yes I just redid the following:

sudo apt purge oem-somerville-treecko-meta
sudo apt purge intel-ipu6-dkms
sudo apt purge libcamhal-ipu6epmtl
sudo apt purge intel-ipu6-dkms

Actuially, when I sudo apt install again all four, on the dkms step I get an error for the 6.14 kernel (I do not know how to remove completely that kernel, even if I purge its source and headers something tells apt to include it in the module compilation)

I hope this does not interfere with vital 6.11 module compilation. Then I reboot and ffplay produces a blank screen.

P:S. I am running 6.11.0-29-generic, of course

Wait so you downgraded to the previous kernel version?

We stayed with the 6.14 and purged the dkms.
