Re: [PATCH 0/1] drm/i915: Allow specifying a minimum brightness level for sysfs control.

Hi, Well, the ACPI spec says this (section B.5.2): " The OEM may define the number 0 as "Zero brightness" that can mean to turn off the lighting (e.g. LCD panel backlight) in the device. This may be useful in the case of an output device that can still be viewed using only ambient light, for ex

Hi, Thus far our assumption always was that the acpi backlight works better than the intel native backlight. So everything only uses the intel backlight if there's no other backlight driver by default. So if I should merge this as a general solution for Windows 8 machines not working properly,
