[Monitors] Monitor goes to sleep when watching YouTube

[faster1]

Having a problem when watching long YouTube videos. My monitor is going to sleep. I don't see any setting to toggle this behaviour. It's good that the monitor would sleep, but it shouldn't happen when watching a video, right? I'm watching YouTube in the Firefox flatpak app. I don't recall this happening with the previous snap installation.

External monitor, or is this a laptop? Specs of either please. And, what version of Kubuntu are you running?

FF *should* report to the OS/Plasma that it is playing a video, even if it isn't full-screen iirc. Not sure if this issue you see is flatpak thing or not.
I see it sometimes in the deb packages for the browser, but not when playing a movie using a video player.

But you can toggle this off/on from the battery or Power Management icon in your system tray if it is acting up.

Kubuntu 24.04 on my desktop PC with a Gigabyte M32Q monitor.

Still having this issue. Anyone have ideas?

The monitor itself has settings. Have you examined those for inactivity/sleep conditions?

I tried that, but the only thing the monitor has is an auto-off setting, which I have disabled. The issue only happens in Kubuntu, and is not happening when I boot into Windows 11. I have a dual boot system. Kubuntu just isn't recognizing that a video is playing in the browser. It sleeps the monitor, and locks the user account.

I like this functionality for normal use, but I don't want it to happen when I watch videos.

Are you using Plasma (Wayland) or Plasma (X11) when you login to the Desktop? I would see if using the 'other' has any effect.
