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
as modules. I have installed spicctrl
To start I can't change the brightness with spicctrl. I i run for example
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?
