Priority: medium
Bug ID: 75917
Assignee: dri-devel@lists.freedesktop.org
Summary: backlight switches of when starting X since
kernel-3.13
Severity: normal
Classification: Unclassified
OS: All
Reporter: nl@gnuffy.net
Hardware: Other
Status: NEW
Version: XOrg CVS
Component: DRM/Radeon
Product: DRI
After updating from linux 3.12.8 to 3.13 my display backlight
switches off when starting X.
The kernel doesn't crash, it just switched off the backlight.
Hardware name: Acer Aspire 3820T/JM31_CP, BIOS V1.19 10/27/2010
This is a notebook with an intel/radeon hybrid graphics.
I use intel for my X. I report this as radeon problem because
git bisect (on linux-stable tree) showed the following commit
as the cause of my problem:
10ebc0bc09344ab6310309169efc73dfe6c23d72 is the first bad commit
commit 10ebc0bc09344ab6310309169efc73dfe6c23d72
Author: Dave Airlie <airlied at redhat.com>
Date: Mon Sep 17 14:40:31 2012 +1000
drm/radeon: add runtime PM support (v2)
This hooks radeon up to the runtime PM system to enable
dynamic power management for secondary GPUs in switchable
and powerxpress laptops.
v2: agd5f: clean up, add module parameter
