Change brightness with Fn keys


I have a sony vaio tx2 laptop. I have some trouble trying to fix the FN-keys for adjusting the brightness on it.

I have tried to follow the advices on this homepage.
I have loaded sonpi and sony_acpi as modules. I have installed spicctrl and sonypid.

To start I can't change the brightness with spicctrl. I i run for example
spicctrl --setbrightness=255
and then
spicctrl -B
I will get 255 as output but the brightness on the script won't change.
Then when I have started sonypid and press for example FN+5 I will get the output:
Event: Fn-F5 Pressed
Event: Event unknown!
echo X > /proc/acpi/sony/brightness
I can change the brightness...

Does anyone know how to solve this?
