Bug Description
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?

It's not a problem with ubuntu- system- settings; opening a task on powerd (the daemon which controls this)
