From ab7027de5c01e4fba0e5ef946f0db27b2e3d799d Mon Sep 17 00:00:00 2001 From: Martin Kepplinger Date: Mon, 23 Jun 2014 22:30:46 +0200 Subject: [PATCH] ACPI / video: Add Acer TravelMate B113 to native backlight blacklist Fix backlight control for Acer TravelMate B113 Laptop by adding it to the video_dmi_table. A workaround before that was to use acpi_osi=Linux or acpi_backlight=vendor on boot but even then, only the function- keys worked. With this change there is no need for boot parameters and DE's controls work as well. Signed-off-by: Martin Kepplinger [rjw: Subject] Signed-off-by: Rafael J.
