Samsung R580, Ubuntu 10.04 and Brightness control

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 »


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

thanks to this forum entry (end of page) :

Have fun !
