993281 - screen doesn't turn off automatically anymore

Status: RESOLVED FIXED

(Firefox OS Graveyard :: Gaia::System, defect)

Description

[David Baron :dbaron: (⌚️UTC-5, no longer working on Mozilla)]

Today I upgraded my self-built hamachi (which runs master):

 from:
   old gaia 99c3fd7a68790173939b9df891c7a8b384c613d4
   old gecko 7bacc9e903b0 plus local patches
 to:
   new gaia c4468bc33303dac135f6acf1e18b3a6a2473f92c
   new gecko d8b2e3738785 plus local patches

After this upgrade, the screen just doesn't turn off anymore unless I press the power button.  If I put the phone down while the screen is turned on -- lockscreen on or off, plugged in or not (though I admit I only tested 3 of the 4 combinations), the screen just stays on in its current state.

I checked in Settings that the display timeout is set to 1 minute.  (I haven't changed it recently, if ever.)

(I have previously done things since the last reboot that caused many apps to be OOM-killed, in case that's related, although I suspect not.)

I also noticed this on my keon.

Seems like this was caused by https://github.com/mozilla-b2g/gaia/commit/86ff94b32e369a925b79ae16ced141c1ac36fc0e which is a backout of bug 933035.

Comparing the original PR https://github.com/mozilla-b2g/gaia/pull/14732/files and the backout https://github.com/mozilla-b2g/gaia/commit/86ff94b32e369a925b79ae16ced141c1ac36fc0e shows that this might be a bad backout :(

Tim, Greg can you take care of this?

I'll re-land it and test if this bug still occurs. Thanks for reporting.

Should be fixed with the relanding of bug 933035.
