How can I make the brightness change in smaller increments?
I red this before (How to increase the screen brightness control sensitivity?), but I didn't find the solution to help in my case.
My laptop brightness is controlled by vendor specified hotkey (Fn+← & Fn+→), so there is no interface for OS (Ubuntu 12.10) to adjust brightness.
When I try to adjust, the slider moves by steps of 40% (0-40-80-100 & 100-60-20-0). Is there a way to set the steps by 20%?
