Issue of Backlight with Fn/F2 & F3 keys in Mint 13/14/15

First of all, check 'acpi' in terminal. If you don't have it then:
sudo apt-get install acpi
If you are not able to change backlight with FN keys (F2/F3 or F5/F6 depending on your keyboard style), there's a simple way to do that. But you need to alter a very important file on your system:
sudo gedit /etc/default/grub
look for the following and alter it to be exactly as you see:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="
GRUB_CMDLINE_LINUX="acpi_backlight=vendor"
save and close. Back in terminal, make sure to save all your work because you're going to update system boot grub and restart.
sudo update-grub && reboot

Ty very very much for the solution. Have been trying to switch from windows with all kinds of distributions, but none has helped me the bright annoyingly screen.
And Mint has always been my first choice.
This works perfectly on an Asus G53JW with mint 17.2
Txh a lot!!
reply to tpaquin,
I think that you did update grub with no problems at all,
next time just seperate "sudo update-grub && reboot" into two commands:
sudo update-grub
sudo reboot
that's all.
Thank you very much. I had this problem in Acer Aspire 5732Z laptop, using Linux Mint 16 - and your tutorial completely solved this problem!!! I'm very happy. My eyes are red though... tommorow will be fine.
