Dell Inspiron 15 3593 Webcam problem on Linux
De Octet.ca
I've just intalled Lubuntu 20.04.1 (Focal Fossa) on a brand new Dell Inspiron 15 3593. No dual boot. I have a problem with the webcam: while it is working, the image is very noisy (grainy).
Described on the feature section on the Dell website as Integrated widescreen HD (720p) Webcam with Single Digital Microphone.
It is a Realtek device that seems to be supported for Ubuntu 20.04:
The device is supported by kernel versions 2.6.26 and newer according to the LKDDb

Video[modifier]
This is a video taken with this camera (native size, we can see that images are noisy).
- Video with the webcam under Linux Ubuntu 20.04
- From dudes on YouTube:

Solutions already tried[modifier]
- Update the BIOS to version 1.12
- Look for new drivers on Dell web page
- Installation of guvcview and QT V4LU to check if the camera settings are ok
- Connect another camera with USB (image resolution is fine)
May help to find a solution:
