I recently installed Ubuntu 12.04 32 bit in my Toshiba T110 laptop, and the brightness control doesn't work.

I have tried gedit /etc/default/grub, and have modified the "quite splash" to many suggestion that i have come across, like:

"quiet splash acpi_backlight=vendor"
and "quiet splash acpi_osi=Linux"
and "quiet splash acpi_osi=Linux acpi_backlight=vendor"

but nothing seems to work, I mean i can see the brightness indicator moving but the brightness is set to highest all the time, Please help.

I got this to work running the following:

first I updated the kernel with the line
sudo apt-get install linux-image-generic-lts-quantal

then I updated the x stack with the line
sudo apt-get install xserver-xorg-lts-quantal

after that I ran sudo gedit /etc/default/grub I modified where it says "quite splash" to "quiet splash acpi_backlight=vendor" saved it.

updated grub using sudo update-grub , rebooted the system and now the "FN" works like magic
