I'm running FreeBSD 10-STABLE on a Lenovo notebook, using Intel HD4000. Everything works perfectly, but the increase/decrease brightness button does it 1 by 1, so I have to press 99 times down, to get from 100% brightness to 1%.
Also xev doesn't recognize the key, I guess ACPI consumes it before it can be reached by X.
Here is
And using
Maybe the only solution is to modify the default AML, but I'd like to know if there's a simpler way.
