LM11 x64 nvidia gforce 330m: adjust screen brightness
I can't seem to adjust screen brightness in AC or on battery.
(1) Fn togggle with arrow up/down does not work at all
(2) This fixhttp://ubuntuforums.org/showpost.php?p= ... stcount=12 also does nothing
(3) Using the nvidia settings "color correction" [as suggested here http://www.pramonotunggul.com/how-to-ad ... rightness/ ] and using the brightness slide bar seems to work, but this has to be setup each time i switch from AC to battery--it is not automatic
(4) Power Manager also refuses to budge
(5) Ubuntu Tweak Power Manager also does nothing
I have searched and tried implementing most of the solutions, but I still find myself struggling to get the brightness honor power management and Fn key (user induced change).
Please can anyone with the right mind help me.
Regards,
SL

Re: LM11 x64 nvidia gforce 330m: adjust screen brightness
It worked like a charm. Many thanks.
Problem [solved].
So, how is someone new to LM supposed to figure this out? is it a bug? Will it be included in future updates? Is it a nvidia specific issue?
Just curious.

Re: LM11 x64 nvidia gforce 330m: adjust screen brightness
Not a bug
Next time just ASK before you stress it lol.
What ya did was told grub that LINUX will control the acpi and not bios.
Windows uses bios to acpi code to allow them to talk to each other via 3rd party, this is only possible if they release the code to be included into the kernel.
Just a little powered by the worlds largest monopoly bs my friend.
Thous that know, know not to buy into the BS and bypass it lol.
Your now in the know.
Wont be the last time you will need to bypass some bs.

Re: LM11 x64 nvidia gforce 330m: adjust screen brightness
The reason I asked was previous editions of LM worked fine; I did not have to instruct kernel to use Linux OS to control the brightness; this has changed since then? or did I miss something in the interim.
But your point is well made. That is why I use Gnu Linux, I like the way it makes me be "in charge" rather than been told that "this is only way to do it."

Re: LM11 x64 nvidia gforce 330m: adjust screen brightness
In this case, some support for your acpi was removed from the kernel or os.
It happens, support for some hardware does get removed to keep sizes in respected amounts.
LTS tend to keep support for hardware longer.
There is just no way to include support for YEARS of hardware in each release.
We end up with a windows 7 bloated all to hell lol
LTS builds have always ended up being much larger once all updates are installed.
at the same time LTS lacks support for state of the art systems and or features.
Thus, why we have new builds.

Hi guys,
I had the same problem, not being able to change the brightness. I did what you described, which brought me a little further, but still not to my full desire ;p
I am now able to adjust the brightness, but it wont change until I restart my laptop. What I mean ist, that it doesnt change right away, but once I fully restart my laptop. Thats not really what Id like to do every time. Do you have any idea?
Thanks in advance,
joha

I got an ACER TravelMate 8473TG - the Nvidia Optimus is deactivated in the BIOS.
The vendor - try did not work. With the vendor -thing I couldnt even adjust anything nomore, meaning that the Brightness-Notification didnt even show up
