[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Hans de Goede <hdegoede@xxxxxxxxxx>

[ Upstream commit bd5d93df86a7ddf98a2a37e9c3751e3cb334a66c ]

Linux defaults to picking the non-working ACPI video backlight interface
on the Lenovo ThinkPad X131e (3371 AMD version).

Add a DMI quirk to pick the working native radeon_bl0 interface instead.
