Thinkpad E495, internal webcam doesn't work.

I have no idea which logs may help with troubleshooting the problem, so I will include everything I can think of. Please let me know if I should upload anything else.

~/ ls /dev | grep video

Has no output.

TL;DR

Hi, I have found a workaround : uvdvideo driver allows some quirks to manage buggy devices.

For this, this is what works for me :

1- Unload the driver : rmmod uvcvideo
2- Reload the driver with the correct quirks : modprobe uvcvideo quirks=4

If this makes the webcam work, create a /etc/modprobe.d/uvcvideo.conf file and add the following line to it:

/etc/modprobe.d/uvcvideo.conf

this makes the uvcvideo module load with quirks on startup.
