The screensaver should not be inhibited by "cpu" and "high-priority" wake locks. It looks like those are used to inhibit GC or disable power save (see Bug 872430).
I've found two screen related wake locks - "DOM_Fullscreen" (Bug 805017) and "screen" (Bug 868325). I think any element which wants to inhibit screensaver should create the "screen" or "DOM_Fullscreen" wake locks - like the VideoElement does. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/434476 Title: screensaver starts while playing HTML5 videos To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/434476/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
