Hi everyone, i have an acer aspire v3-771G, with Fedora 19 installed with xfce graphic environment (but i also tried with Gnome and kde) and i can't change the monitor brightness, it is set to maximux, i tried to change it from the BIOS but it didn't work and i also downloaded the Gnome applet, same result ... i'm going blind!

yes , your answer work fine in gnome,kde,xfce,mate and cinnamon , but in lxde this isn't work inclusive the grub conf is the same but the brightness control not work , the only way is install xbacklight al later in a terminal run xbacklight set -x .
I am just and Gnome user :) Thats i havent knowledge of lxde or xfce :(
Hey Andrea,
Follow these steps, After them you will definitely control brightness.
sudo gedit /etc/default/grub (Gedit is notepad in Fedora)**acpi_backlight=vendor** just replace these words from rhgb quiet acpi_backlight=vendor"grub2-mkconfig -o /boot/grub2/grub.cfg (For legacy bios).Enjoy Fedora :)
I seem to have forgotten the default grub settings after following your instructions. Could you help me out?
