I just tried the same kind of proto handset rsalveti mentioned side by side with a production Ubuntu edition device. Both devices appeared to still show a (dim) backlight at the lowest setting the UI allowed.
I could see that the screen backlight went all the way off when the device was turned off with the power button. Is there some other step (setting auto brightness, tweaking something else?) we need to do to see the effect you observe? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to indicator-power in Ubuntu. https://bugs.launchpad.net/bugs/1436538 Title: brigtness slider should not allow total darkness Status in indicator-power package in Ubuntu: Incomplete Bug description: bq aquaris 4.5, Utopic Unicorn 20150312-002053: slider allows to minimize the brightess to the point of not seeing at all.
