Running Ubuntu 10.04 LTS on a Samsung NF310. Most of it works right out of the box. But the function keys controlling the luminosity of the screen freeze the mouse and/or the screen and don't seem to work correctly in any way. This page is a collection of links and possible solution to overcome this problem.

Following 79 Delta Charlie solutions:

Add Samsung-tools and Samsung-backlight from Voria repository

sudo add-apt-repository ppa:voria/ppa
sudo apt-get update

Edit /etc/default/grub and replace:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

by

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

Save the file and then do:

sudo update-grub2
