I did this to my Acer 5742z-4685 Ubuntu 10.04

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash acpi_osi=”

this fixed the brightness but, the icon don’t show wile changing, strange, the icon worked when the fn+brightness didn’t, the volume works fine..

hope this helps everyone..good luck….

Hey Deepak, thank you for the tip, I also have an Acer Aspire 4736 and now I can finally change the brightness of the screen.

The only problem now is that is working in the oposite direction, the brighter button makes the screen darker and vice-versa.

In my Acer Aspire 4736, following change worked. In /etc/default/grub,

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash acpi_osi=Linux”

How could I get this to work for the volume keys on my laptop, it has two of the f keys mapped to volume when you hold down the fn key but when I use them the volume goes nuts all over the place?

is not working with HP Probook 4310s (ATI 4330)

brightness sets manually here: /proc/acpi/video/DGFX/LCD/brightness

but using ”acpi_backlight=vendor” now it says:
cat /proc/acpi/video/DGFX/LCD/brightness
