Asus laption integrated camera not detected
By David Jones •
Laptop Asus UX330UAR. Integrated webcam is not detected by the OS - Ubuntu 18.04. Both Cheese and guvcview complain - no device.
Q: What to check/try for fixing? Considering it was definitely working with Ubuntu 16.04...
All checks made after fresh reboot.
I wasn't expected that, but seems uvcvideo is not loaded after start up:
sudo rmmod uvcvideo

Looks like that's HW problem. Probably due to quite limited angle (as designed) of opening of the monitor-cover some bus-cables damaged.
