Hello!

The integrated webcam is not shown at all in skypeforlinux/discord/cheese/chrome. The external webcam is shown, but the content is just black.
I have dual boot with Windows 10. The integrated webcam works there and the external one (Genius Eye 312) started to work after I installed its driver.
My laptop is ACER Nitro 5 AN515-58-789C and I found no keyboard shortcut in the user manual.

The system report: https://www68.zippyshare.com/v/Vf6ljuUW/file.html
I figured that the internal webcam is 0408:4035 Quanta Computer, Inc. ACER HD User Facing in lsusb.

cat /dev/video0 shows No such file or directory


sudo dmesg | grep -ni "uvc|facing":

Code:

The lines with "Failed to query" and "Failed to initialize" are with red.

EDIT:
The integrated camera was fixed with help from here https://bugs.launchpad.net/ubuntu/+sourc...ug/2000947.
But the external one still isn't working.
