BugLink: http://bugs.launchpad.net/bugs/1332437 The ACPI backlight control is broken on these 2 models. Since backlight control works on 3.16.0-999-generic #201406200205, and also works on 3.13.0-29 with video.use_native_backlight=1. Add use native backlight quirk for these 2 models as the workaround. This patch can be ignored after 3.16-r2. Changes v1 -> v2: - exclude Dell Inspiron 5737 from quirk Signed-off-by: Edward Lin <yidi.lin@canonical.com> --- drivers/acpi/video.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+)
