[Bug 1393160] [NEW] Backlight control not working; but entries in /sys/class/backlight.. Vendor: American Megatrends Inc.. Version: 5.6.5
Public bug reported:
Hi there,
First of all sorry for my broken english.
Backlight control does not work on my LDLC Mercure MA1-4-HS5 Slim (Vendor: American Megatrends Inc. Version: 5.6.5) with Ubuntu 14.04.1 LTS (Release 14.04).
I tried to fix this with Xbacklight but it does not work either.
Here are a few information I can give, I hope it will be useful...
Thank you for your time !

Bug description:
Hi there,
First of all sorry for my broken english.
Backlight control does not work on my LDLC Mercure MA1-4-HS5 Slim (Vendor: American Megatrends Inc. Version: 5.6.5) with Ubuntu 14.04.1 LTS (Release 14.04).
I tried to fix this with Xbacklight but it does not work either.
Here are a few information I can give, I hope it will be useful...
Thank you for your time !
