No Camera Found laptop (Microsoft Surface Book 2)

Front & back cameras appear to be supported for Surface Book 2 but I'm still not sure what I need to do: https://github.com/linux-surface/linux-surface/wiki/Camera-Support

https://turlucode.com/how-to-install-ubuntu-18-04-on-surface-book-2/

Seems there is a custom kernel to make stuff work.

I tried everything starting from 'Install linux-image-surface kernel" to "Post installation" but the camera still isn't working. Please let me know if there is anything else I can try.

For diagnostic purposes, what output do you receive for the commands (to be executed in a terminal window):

uname -a
lsb_release -crid
sudo lsusb
sudo lspci
sudo dmesg | grep -i -E 'firm|cam|ipu|ov5|ov7|ov8|ov9'

(not sure whether it will help, though)

I've tried a bunch of solutions, so perhaps that's why I still can't get it to work. But here's the output from a copy/paste of the commands from above...

The log files show two cameras (probably front and rear). What output do you now receive for the command

cam --list

Here is what I get from cam --list

cam: command not found

cam is contained in the package libcamera-tools

Hmmm, not sure what that means I typed "libcamera-tools cam --list" & got this: libcamera-tools cam --list.

I just googled install libcamera-tools & found this: https://libcamera.org/getting-started.html
I copy/pasted the code at the top in terminal & got this:

I've been trying different things & found this: https://github.com/linux-surface/linux-surface/wiki/Camera-Support but none of the commands work. I think I found the bin files but they are in a zst that I don't have permission to uncompress. All other commands return results that include "command not found", so I'm clearly doing something wrong.

This is a fresh install, I'm don't know why this is so messed up already.

You misunderstood "cam is contained in the package libcamera-tools"

You have to install the Ubuntu package libcamera-tools and this will provide the application "cam".

Either in a terminal execute the command

sudo apt install libcamera-tools

or search in the software center (or in synaptic, or other package management tools) for the package libcamera-tools and install it from there.
