There are some scenarios make turning off brightness not desirable, e.g. an AIO user changes brightness to the lowest level in unity-control- center, he can't change it back if his keyboard does not have brightness hotkey.
Since we can't ensure that all graphics driver have the same mechanism and each one of them does not change, I think it's a better choice to let userspace program controls a consistent policy. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1381625 Title: Adjust brightness to lowest value caused screen whole black Status in HWE Next: Confirmed Status in Unity Settings Daemon: Fix Released Status in linux package in Ubuntu: Confirmed Status in unity-settings-daemon package in Ubuntu: Won't Fix Bug description: [Impact] When adjusting screen brightness to lowest value, it turns screen backlight off.
