--- Comment #2 from Nicholas Kazlauskas (nicholas.kazlauskas@amd.com) --- At some point we started reading the ACPI backlight caps to respect the actual backlight range for the panel. We map the backlight level specified by the user from 0-255 to that range.
In the case where the caps aren't valid we use a default minimum brightness that's non-zero since some panels will flash when the backlight level goes to zero.
While I don't know offhand the reasoning for 12 specifically I also don't think we'll be dropping it back down to zero.
Wouldn't DPMS off give you what you want in this case?
