[Bug 1502145] Re: Apps can keep screen lit permanently
The original report for the browser was closed some time ago so I suggest we need a new bug. Per comment #27 this may be a new behavior with the new repowered in ota13. (I added lp:1630986) Per comment #25 I think this is actually functioning as intended, if an app sets display on and is an active app we honor it. What is missing IMO is any indication that this is the state of the display. Also would be nice to add display on to the app permissions controlled via settings.(lp:1630989) ** No longer affects: qtmir (Ubuntu) ** No longer affects: unity-system-compositor (Ubuntu) ** Changed in: canonical-devices-system-image Status: Confirmed => Fix Released ** No longer affects: unity8 (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1502145 Title: Apps can keep screen lit permanently To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1502145/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It's very easy to reproduce now. Just run an app that requests the screen to stay on, in my case ubuntu-silo-installer (click package attached). Steps to reproduce: - launch the app - press the power button to lock the phone/dim the screen - now send a text message to the phone Expected results - screen turns on for notification, then goes black after timeout Actual results: - screen turns on for notification then stays on Seems to happen even if you move the app to the background before turning off the screen. Whenever the screen is locked or hte app is moved to the background we should remove the lock that is causing the screen to stay on. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1502145 Title: Apps can keep screen lit permanently To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1502145/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm reopening the unity-system-compositor task, because the bug still exists there. Even if oxide will lift the screen lock when unfocused, who's to say other apps will behave well, too? We need to make sure that only the foreground app can request a screen lock, which means we need to refactor how it works and have the shell proxy the requests to u-s-c. ** Changed in: unity-system-compositor (Ubuntu) Status: Invalid => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1502145 Title: Apps can keep screen lit permanently To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1502145/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1502145] Re: Apps can keep screen lit permanently
Thanks for the detailed analysis Alexandros. I am able to reproduce the issue reliably on my arale, looking into it. Note that the fact that keepDisplayOn is requested twice is expected: chromium instantiates one PowerSaveBlocker per stream, so for a video with audio, that’s two streams, hence two requests. Perhaps not the most efficient thing to do, but it should be okay as long as the corresponding removeDisplayOnRequest requests are emitted where relevant. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1502145 Title: Apps can keep screen lit permanently To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1502145/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1502145] Re: Apps can keep screen lit permanently
I have found a way to deterministically reproduce the issue with webbrowser-app. Perhaps there are other scenarios that are problematic, but hopefully this will at least provide some hints. Below are the steps and between them the USC logs I get for each step, which give some insight into what is going wrong. [TL;DR] The problem seems to be that, for some reason, if after the screen is turned on and logging in the webbrowser is in focus and playing a video (which means that the user previously turned off the screen with the power button while playing a video in the browser) the webbrowser app leaks (doesn't eventually release) two keepDisplayOn requests ids. This causes the screen to stay on even when focusing away from it. [Detailed analysis] 1. Start browser, start watching a youtube video. The browser requests keepDisplayOn twice from two different dbus connections, which is strange, but OK. [1444841076.023016] usc::UnityScreenService: Received request with serial 3 from :1.300 : keepDisplayOn [1444841076.023390] usc::UnityScreenService: Sending reply for serial 3 to :1.300 id: 9 [1444841077.052913] usc::UnityScreenService: Received request with serial 3 from :1.301 : keepDisplayOn [1444841077.053164] usc::UnityScreenService: Sending reply for serial 3 to :1.301 id: 10 2. Turn off screen with power key. Everything is normal the keepDisplayOn requests are released.

[Bug 1502145] Re: Apps can keep screen lit permanently
Oxide (the web engine under webbrowser-app) is the one that issues a request to prevent screen blanking when playing a video. It has code to handle releasing the lock when the app goes into the background, so unless the signal doesn’t reach oxide in time before the process is stopped, the lock should be released as expected. See oxide::PowerSaveBlocker::ApplicationStateChanged() in http://bazaar.launchpad.net/~oxide- developers/oxide/oxide.trunk/view/head:/shared/browser/oxide_power_save_blocker.cc#L238. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1502145 Title: Apps can keep screen lit permanently To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1502145/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
