Comment 3 for bug 840683

Could someone please explain the meaning/purpose of 'Dim screen to save power'? This bug's reporter says that it doesn't have any effect on screen dimming when on idle and on battery. I can also confirm this behaviour. However, in bug 844241, the screen is dimmed but isn't restored on activity but the dimming doesn't occur if the checkbox isn't checked. That bug is also reported against Oneiric.

Would this mean that there are two bugs on screen dimming: one/this bug about dimming not working at all with misleading description for the checkbox and the second one about broken brightness restoring on activity after idle? Or should the misleading description moved to a new bug?
