You could use the Screen Wake Lock API to prevent the screensaver on Chrome browsers: https://developer.chrome.com/articles/wake-lock/ https://developer.mozilla.org/en-US/docs/Web/API/Screen_Wake_Lock_API

I just tried it locally. Had everything closed but Firefox in the first test run and Chrome in the second test run. The other call participant was on a different device to not interfere. OS was Ubuntu 23.04

So screensaver started nor did the screen lock, which happened after the 1 minute was over from ending the call.

I had the same issue twice this week.

No camera on, but I was actively speaking and my screens turned of. I was using Chromium on Ubuntu 🐱

Can reproduce on Chrome and Talk Desktop. A bit weird, because a web-browser should keep the machine awake when there is video/audio playing.

Screen Wake Lock API should solve the problem, but it is not supported by Mozilla.

We can use Wake Lock API with a polyfill that just adds hidden small video in a background.
