Automatic brightness controll stopped working in OTA-22 on Volla Phone X

[Talkless]

Description of the feature

Discovered that after OTA-22, enabling brightness control in battery indicator no longer starts to control screen brightness.

• Device: Volla Phone X
• Channel: Stable
• Build: OTA-22

Steps to reproduce

Enable automatic brightness inside Battery indicator or in system settings.

Expected behavior

Screen brightness should be adjusted depending on environment lighting after enabling that feature.

Actual behavior

Screen brightness is not automatically controlled. I can adjust it manually though.

Logfiles and additional information

tail -f ~/.cache/upstart/*.log shows nothing related while switching brightness control off or on.

Please attach rather /var/log/repowerd log right after restart of the device, thanks!

I just noticed that the automatic brightness does not work in OTA-22 on Pixel 3a

[Flohack74]

I also have problems on SHIFT 6mq with autobrightness on devel channel. So it might be a regression we missed. We will look into repowerd commits.

[lduboeuf]

Does OTA-23 fixed the issue ?

[Flohack74]

No its even better, I reinstalled it with bootstrap on devel since @amartinz told me its working for him. Then autobrightness started to work, but only after next reboot. Now its again broken

[amartinz]

I have done some more extensive testing and noticed, that this could be a race condition.

Whenever it stops working, i got the following log prints: Error org.freedesktop.DBus.Error.ServiceUnknown: The name com.canonical.powerd was not provided by any .service files

If i then restart repowerd (service repowerd restart) autobrightness starts to work again.

Repowerd is configured to start right after dbus and the android container are up:

• start on started dbus and android

Maybe it helps to delay start of repowerd to give it some more time and move it to start after lightdm is up?

• start on started dbus and lightdm

[Flohack74]

I think we should delay it after sensorfw since before we had only a dependency on libs but now its a service, so unless this is started no brightness values could be read, and repowerd will not retry to inizialize that connection, rather it resorts to using a dummy driver that does nothing.

[Talkless]

Any news with OTA-23 rc? I an mot sure I want to install RC on my daily driver... Or maybe I should?

[Flohack74]

Wie release RC to stable tomorrow, so :P

[Talkless]

So I guess more months with bug-ridden Volla Phone :(

[Flohack74]

@Talkless well I dont own the device, I cannot test it and help you. I also see intermittent problems with autobrightness on Halium 10 devices, as there is a race condition for stsartup of sensors. We will look into this in the next OTA, but not sure it will fix your issue.

[Talkless]

Issue exists on OTA-23 too.

[Flohack74]

Does actually manual brightness work?

[koenvervloesem]

I'm on a Volla Phone X with OTA-23 and manually setting brightness works, but automatic brightness control doesn't seem to do anything.

[fredldotme]

It could be fixed by this commit on devel: https://gitlab.com/ubports/development/core/repowerd/-/commit/86e26b9360e2b54dafc9c2fcac8f777e97ae66c3
