From bd5d93df86a7ddf98a2a37e9c3751e3cb334a66c Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 17 May 2023 11:23:59 +0200 Subject: [PATCH] ACPI: video: Add backlight=native DMI quirk for Lenovo ThinkPad X131e (3371 AMD version) 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. Signed-off-by: Hans de Goede Signed-off-by: Rafael J.
