Ubuntu 14.04 LTS: FN-Brightness Key Stopped Working

Question

Hello dear Ubuntu Community,

After i installed some Ubuntu Updates on my PC,my FN-Key stopped working. (But i can still change it in the System settings. I tried many ways to fix it trough the /etc/default/grub file.

My actual entry is:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi= acpi_backlight=vendor" GRUB_CMDLINE_LINUX=""

I have a Acer Aspire E1-510 with Intel Inside PENTIUM

Please Help me :/

[PS: Sorry for my bad English i'm German]

ON my acer asus 1005PE, I need acpi_osi=Linux to have it working. — Rmano, Nov 22 '14 at 11:42

Please try:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"

It works at least for me on my acer asus 1005P, contrary to what it's written here. (maybe the kernels are different).

I fixed it with this entry in /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux" 
GRUB_CMDLINE_LINUX=""

Thanks to Rmano
