I know this is a commonly asked question, but some function keys dont work (Fn + F5, F6, C, V and Space). I got the Asus eeePC F201E-KX067DU which came shipped with Ubuntu 12.04 LTS and after the first boot-up every function key was working out of the box. I changed the OS to Ubuntu 12.10 and since then some Fn keys didn't work anymore (I also tried installing 12.04 LTS again to see if those keys work again).
I already searched for some hours now, without any results ... editing /etc/default/grub with:

GRUB_CMDLINE_LINUX_DEFAULT="nosplash acpi_osi=Linux acpi_backlight=vendor"


GRUB_CMDLINE_LINUX_DEFAULT="nosplash acpi_osi="

doesn't seems to work.
