Internal laptop camera disconnecting every 30 seconds

[João Pimentel]

Since some months ago, the web internal camera of the laptop simply disconnects after 25-30 seconds and then reconnects again. In some video software the camera reconnects and I have to bear with a blink every 30 seconds and in other platforms such as in zoom the video simply freezes.

## Features

- A Toshiba Satellite laptop
- Ubuntu 18.04 LTS
