 i want to suggest a new configuration option which would be benefical to
 power management.
 Today, if i have my phone powered (eg. not suspended) and locked, the
 screen light will dim. However, since i locked my phone (via aux button),
 it is very likely that i put it into my pocket where the display will
 regularly come into contact with something. Currently, this will activate
 the light of the screen, wasting energy.

 Most commonly users will unlock the phone if they want to read something,
 but i thnik it would be the best if the new behavior would be
 configurable, so users may further adjust screen blanking to their needs.
