I managed to fix the brightness issue on my Dell M1530, Ubuntu 10.04. The Fn key worked but the notification was out of sync. Adding the acpi_backlight=vendor to the grub command line solved the problem. I edited the /etc/default/grub file, GRUB_CMDLINE_LINUX row. Remember to run sudo update-grub2 and sudo update-initramfs -u after editing the grub file. After reboot it will take effect.
