No brightness adjustment on samsun n210 (Intel GMA 3150)

[vimm]

Hello folks,

I installed Ubuntu Remix on my netbook samsung n210. Most of features work fine (some don't OBVIOUSLY) but there is one annoying problem - BRIGHTNESS. I cannot adjust it and unfortunately it's default to the lowest. It's very difficult to work on it.
Of course problem is deeper then invalid key bindings.

It looks like default video driver doesn't support brightness correction for my card. I have nothing related to it in my /proc/acpi or /sys/. "Randr" doesn't know brightness option as well.

My video card is: Intel GMA 3150

Does enybody know how to fix it? I just want to use 90% brightness do I have to look for different drivers or something?

Thank you.

Check out this thread: http://ubuntuforums.org/showthread.php?t=1313390.

Various options seem to have worked for some. The title is misleading in saying 'Dell laptops', as if Dell had some special hardware made only for it's products.

Thank you for this link it helped in a way... Amendments to grub config only ******** it up however I discover I can change my brightness on grub screen and it will persists for the whole ubuntu session

Are you saying that brightness keys work at Grub menu, but not after?
It's always a good idea to backup any config file before editing, in this case /etc/default/grub. In case the change makes the system unbootable, you can restore the file to its default.

sudo cp /etc/default/grub /etc/default/grub-backup

I wouldn't say "it works in GRUB" it's rather "it works outside UBUNTU".

I have a Toshiba NB305 with Intel GMA3150 and the screen brightness does not work when I install 9.10.

I've tried to install 9.04 and the screen brightness worked, but the resolution was screwed up (800x600).

Anyway I've gone thru most of the remedy that was posted in the forum already. Any help would be appreciate.

Try this:

sudo add-apt-repository ppa:voria/ppa
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install samsung-tools samsung-backlight
sudo reboot
