Public bug reported:
Bus 003 Device 002: ID 04f2:b71f Chicony Electronics Co., Ltd Integrated
Camera
Does not work on 22.04.5 (kernel 6.8, and I can't find a 22.04.4 download link
for an older kernel. Some random forums on the web claims it worked on 22.04 on
earlier kernels).
Does not work on kernels 6.8-6.14 on 24.04
Does not work on kernel 6.18 on 26.04-snapshot3
Example: Lenovo Thinkbook Yoga
I tried loading the uvcvideo module with quirks=640
I tried systemctl --user restart pipewire wireplumber
I tried sudo apt install pipewire-libcamera
And it is not working.
Here is running snapshot on the command line on 26.04.-snapshot3:
