Inconsistency in power management brightness adjustement

[Kevin DuBois]

In the Power Management configuration program, the display brightness on "On AC Power" is set relative to 0% whereas under "On battery power" it is set relative to 100%. This is a minor annoyance that is easily changeable, I would imagine.

I was about to report this bug :) I'm actually not even sure the OP is correct. Under the AC power tab you set display brightness from 0-100 and how this works is obvious. Under the Battery power tab you set "Dim display brightness by" instead. I'm not sure if this is how much it will dim the display by if "Dim display when idle" is checked, how much it dims the display relative to when on AC power, or as the OP said relative to 100%. However it is, it would be more consistent and less confusing if under both tabs there was simply the option, "Set Display Brightness To" and rely on the user's intelligence to set the battery setting lower than the AC one -- perhaps display a warning in red text at the bottom of the window explaining that they probably want it lower.

I agree. It's a very confusing and annoying UI. It took me quite a while to notice, that the slider under Battery tab is actually turned around (the opposite of the one in AC tab).

Maybe it would make sense to merge them, or mark one as a duplicate.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.
