Hey!I installed Fedora 42 the day before yesterday, and unfortunately, the camera doesn’t work, no matter I use camera software like plasma camera, cheese, kamoso, etc., the camera doesn’t work. I tried installing akmod-intel-ipu6, akmod-v4l2loopback and the camera still doesn’t work.Is it that my camera model is not supported or something else?What Should I do?
Linking your upstream report: Huawei Matebook GT 14's camera doesn't work in Fedora 42 · Issue #357 · intel/ipu6-drivers · GitHub
It may not be supported, but additional data is needed.
lsusb -vv -t
journalctl -b -g 'ipu6|camera'
You may also want to take a look at, HUAWEI VGHH-XX Notebooks as was suggested here
Can you post these as preformatted text (</> on the toolbar) vice using screenshots.
Thanks
Sure.

Can you double check
cam -l
v4l2-ctl --list-devices
You might need to install libcamera-tools for cam and v4l-utils for v4l2-ctl.
Looking at what’s here it doesn’t look like it sees the camera at all.

I very confirm that My Huawei Matebook GT 14 has a camera.
