Subject: Re: Linux 3.11-rc2 [backlight] [ASUS N56VZ]

Hi,

it seems a lot of people are complaining about the backlight pull 
request of RC2.

This is to tell you how it saved my life:
- Changing brightness from Fn keys does work
- Writing to /sys/class/backlight/intel_backlight/brightness does work
- Changing brightness from gnome brightness settings does work
--> It seems everything is now working (it wasn't before).
--> I appreciate your patch and I am going to be sad if you revert it :-)


My laptop : Asus N56VZ
My /proc/cpuinfo: 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1030556/+attachment/3241093/+files/ProcCpuinfo.txt
My dmidecode is below.

Changing brightness from Fn keys didn't work on 3.9 and 3.10 kernels.
I a not sure for previous versions though a patch was made for 3.2 in 
ubuntu. See details here:

There are a lot of bugs opened for this:
