** Description changed: + Need to have fix in Bionic, better to have it in xenial. + The minimum brightness of the laptop screen panel may not be realistic sometimes especially when having a problematic screen panel. For example, Dell Precision 5720 AIO only has 9 levels in /sys/class/backlight/intel_backlight/max_brightness because the wrong settings in VBIOS. It is an all-in-one desktop PC and there is no brightness hotkey to control the backlight. When we set 0 to /sys/class/backlight/intel_backlight/brightness, it turns off the panel's backlight and there is no way to brightness up the backlight again so we can only avoid using 0 as the minimum backlight level.
