I did a clean boot with Kubuntu Raring 13.04 64 bits Live DVD. The problem persists exactly the same:
The Fn keys change the value of /sys/class/backlight/acpi_video0/brightness but to change laptop internal screen brightness, it should be changing the value of /sys/class/backlight/acpi_video0/brightness When I changed this last one, the screen brightness changed accordingly. So, I believe this is NOT a bumblebee issue and it seems to be happening only with the Haswell chipset, since I have not found any complains from users with older chipsets using bumblebee or not. After all, it still happens with a clean boot from the Live DVD. Unfortunately, I have no idea what package should be handling this. Maybe KDE itself or LightDM?
