I have two Lenovo Y550 machines, one with Intel graphics and the other with nvidia graphics. The function key brightness works find for the nvidia graphics both with the open source and restricted drivers. The intel card does not work.
Furthmore, there is no folder /proc/acpi/video/VGA/LCD/brightness There is a path /proc/acpi/video/GFX0 but no LCD folder under it. gnome-panel brightness app does not work. It installs and the slider opens but as soon as one clicks, the slider closes. The next time the slider is opened, it is offset about half the value of the screen to the left but still doesn't work. -- [LUCID Beta 1] Brightness Fn keys don't work as expected on Sony Vaio VGN FW35G.
