From ed796e0916a8498b8511d80ddfe0355a58fe5730 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Thu, 19 Jan 2023 17:37:43 +0100 Subject: [PATCH] ACPI: video: Add backlight=native DMI quirk for HP Pavilion g6-1d80nr [ Upstream commit d77596d432cc4142520af32b5388d512e52e0edb ] The HP Pavilion g6-1d80nr predates Windows 8, so it defaults to using acpi_video# for backlight control, but this is non functional on this model. Add a DMI quirk to use the native backlight interface which does work properly. Signed-off-by: Hans de Goede Signed-off-by: Rafael J.
