This is coming from unity8/plugins/Unity/Indicators/qml/SliderMenuItem.qml, which uses the Ubuntu UI Toolkit's slider but explicitly sets the 'live' property to false so that there won't be realtime updates.
I'm not sure whether or not there was a Good Reason it was done this way. Looks like Renato wrote the original version that included the "live: false" line, so assigning him under also-affects Unity 8 so that he can give a second opinion on this ticket. ** Changed in: unity8 Importance: Undecided => Low -- You received this bug notification because you are a member of DX Packages, which is subscribed to indicator-power in Ubuntu. https://bugs.launchpad.net/bugs/1227595 Title: [touch] The screen brightness change is not realtime Status in The Power Indicator: Invalid Status in The Unity 8 shell: Confirmed Status in “indicator-power” package in Ubuntu: Confirmed Bug description: Changing the screen brightness on my touch devices is not real time.
