I really need help on this cause I'm getting crazy, and honestly very disappointed with the stability of ubuntu, because I can't have a normal video-conference with anyone and as you can imagine that is a must nowadays. I searched already a lot in google and here and found no stable solution yet.
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.

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.

- A Toshiba Satellite laptop

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.
