Prerequisites

  • I have searched open and closed issues for duplicates.

Describe the bug

The display turns off after the configured inactivity timeout, ignoring the fact an app runs in full screen mode (e.g. a browser showing a movie, or a Skype video call).

To Reproduce

  1. Go to System Settings > Power and set Turn off display when inactive for to 5 min
  2. Go to YouTube in Firefox and play Cantina Band 10 Hours
  3. Activate full screen for the YouTube video
  4. Remove your hands from Mouse and Keyboard
  5. Start your 5min-Handsfree-Dance
  6. ... eventually the display turns off, but the Cantina Band is still playing it's awesome song

Expected behavior

Don`t disable the display while an app is displaying content in "Full Screen" (= without any window manager header bar)

I'm experiencing display turn offs caused by "inactivity" in a lot of apps - basically for everything which enables me to either watch a movie or do a video call:

  • Firefox
  • Skype
  • Microsoft Teams
  • Zoom
  • ...

Any chance we can somehow detect "real inactivity" instead of just "not moving cursor"? For example: If the focused app is in full screen and generates audio, the display timeout should be ignored.

From Slack:

see https://valadoc.org/gtk+-3.0/Gtk.Application.inhibit.html
but this is per-app, of course
and shouldn't be tied to fullscreen either
instead, browser should call it when starting to play a video, etc

That said, this is an app implementation issue which needs to be fixed per app.
