From mboxrd@z Thu Jan 1 00:00:00 1970 From: Hans de Goede Subject: [PATCH] acpi-blacklist: Remove disable_osi_win8 because of backlight models Date: Thu, 1 May 2014 13:39:09 +0200 Message-ID: <1398944349-9271-1-git-send-email-hdegoede@redhat.com> Return-path: Received: from mx1.redhat.com ([209.132.183.28]:2909 "EHLO mx1.redhat.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1754310AbaEALjS (ORCPT ); Thu, 1 May 2014 07:39:18 -0400 Sender: linux-acpi-owner@vger.kernel.org List-Id: linux-acpi@vger.kernel.org To: Zhang Rui , "Rafael J. Wysocki" , Len Brown Cc: Vincent Gerris , linux-acpi@vger.kernel.org, Hans de Goede When the windows8 related backlight problems became evident, 2 approaches were follow in parallel, one was to stop claiming to be windows 8 / 2012, the other was to tell acpi_video to stop registering a backlight driver (video.use_native_backlight=1). Since commit 170269a9d3c0 (ACPI / video: Default to using native backlight control on Windows 8 systems) in linux-next we're defaulting to video.use_native_backlight=1. This should also fix the backlight control on all models which currently have a disable_osi_win8 quirk, so remove them from the acpi blacklist.
