Little feedback everything is working ok apart from on first boot.

An update: In the latest package release 2016.08.2+16.10.20160823.1-0ubuntu1 I have provided a workaround for the Nexus 4, by applying the last normal brightness value before letting autobrightness take over when turning on the display. This is not ideal, but it's what powerd did in the past, and fixes Nexus 4 to have a quick reaction time. Note that this workaround applies only to Nexus 4. Other devices use the autobrightness setting directly when turning on the display (and autobrightness is enabled, of course), providing a smoother display-on experience. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1613871 Title: Regression: In dark conditions autobrightness does not adapt To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1613871/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1613871] Re: Regression: In dark conditions autobrightness does not adapt
On krillin and arale, this appears to be fixed by silo 31. The fix actually allows the brightness to update even faster, by toggling autobrightness off then immediately back on. By doing that, it can update in less than a second instead of the usual 4.5 seconds. And it actually does update now (immediately) instead of waiting for the first change after it's enabled. In any case, seems to work fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1613871 Title: Regression: In dark conditions autobrightness does not adapt To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1613871/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1613871] Re: Regression: In dark conditions autobrightness does not adapt
After some more experimentation with this fix, I noticed a strange behavior on Nexus4. When autobrightness is enabled and the screen turns on under bright light, the updated repowerd autobrightness algorithm transitions the brightness to a high value (as expected), but the N4 display sometimes doesn't react to this high brightness setting, remaining at an arbitrary lower brightness setting instead. It seems that it takes a screen content update to "remind" the Nexus4 display that the brightness has changed. This problematic behavior is not present on other devices (krillin, arale), and all findings point to some system layer below repowerd as the culprit. This Nexus4 behavior doesn't affect the validity of the proposed fix, since repowerd itself is doing the right thing. I will file a new bug for this Nexus4 specific issue when the fix for this bug lands in the image, so that the problem is easy for others to reproduce. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1613871 Title: Regression: In dark conditions autobrightness does not adapt To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1613871/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1613871] Re: Regression: In dark conditions autobrightness does not adapt
The problem was that the autobrightness algorithm was too slow to react to the first light values after being enabled. This caused both the related issues mentioned in comments in this bug (taeibot65's and jibel's). The fix is in silo 31 and in the process of being merged: https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/landing-031/ in case anyone wants to try before it reaches the stable-phone-overlay PPA and an image.
