Brightness keys and booting the kernel

2012-05-01 Thread Nikolay Tychina
Hi,

Considering the fact that brightness keys work until kernel is loaded,
is it possible to make them work
after the kernel is booted in some simple way?
I remember my previous laptop was able to control brightness without
any acpi_* modules and disregarding
OS running.

Regards
Nikolay

What make and model laptop?  What OS?  (this one, and the previous?)

% head -24 /var/run/dmesg.boot

should provide a clue or two.

cheers, Ian
