For unknown (anyway, for my side) reason, the NVIDIA driver is not well configured after installation on the Samsung R580. In fact, brightness control does not work, with Fn+Keys or using the brightness applet, telling back to you that "Brightness status can not be read in Bios side".

So, in only one line, the issue can be solved: just edit the /etc/X11/xorg.conf file and add the following line (the bold one) into the Device section:

Section "Device"

  Identifier "Default Device"

  Driver "nvidia"

  Option "NoLogo" "True"

  Option "RegistryDwords" "EnableBrightnessControl=1"

EndSection

And that's it ! Brightness control with Fn+keys is working great.

Have fun !

I have just received my new laptop, and have already installed Ubuntu as my default OS. Only one thing remain unreachable, the Brigthness control :(

But, thanks to the voria (https://launchpad.net/~voria/+archive/ppa) PPA , I am able to use, network, Wifi, and all other features as suspend, hibernate and so on.

Ubuntu needed cheat sheet for this PPA:

- deb-src http://ppa.launchpad.net/voria/ppa/ubuntu YOUR_UBUNTU_VERSION_HERE main
