Public bug reported:
Ubuntu 13.10 (r100) (Touch)
Expected: manualy adjusted screen brightness stays that way, except
after period of inactivity, when it goes into power saving mode
Instead: brightness is dimmed after a few seconds
As stated in title, screen brighness adjusts itself constantly: When adjusting
brightness manualy, Galaxy Nexus device (maguro) is often dimmed immedeatly to
seemingly some kind of default setting.
Usualy, this bug happens within seconds after the brightness is set manualy.
Sometimes though, it happens later at (apparently) random moments. On rare
occasions, it doesnt happen at all.
On every occasion however, the slider for manual setting stays where it is.
At first, I was thinking it was triggered by an overzealous proximity
sensor (which however works perfectly on android). Now I am leaning
towards some sort of default setting or automated brightness. Judging
from earlier posts on xda and LP, it seems there was such a feature at
some stage in the beta. is there some kind of automatic brightness
process at work, that overides the manual, but which has no interface?
