I have the same problem with Lenovo Ideapad Y450 laptop. With Jaunty Live CD, the brightness control worked. But after installation and update, it doesn't wok anymore. The file "/proc/acpi/video/VGA/LCD/brightness" is updated with the Fn+arrow_keys, but the bightness just don't change.

If any input is required, I can help too.
