I have ubuntu 12.10 on a Gateway Laptop. Intel processor and Intel video chip.
My keyboard's brightness increase/ decrease keys don't have any effect on the brightness. The brightness meter shows that its decreasing and increasing, but the actual brightness remains at the highest level at all time.
Also, i am unable to change the brightness form Brightness and Lock. the Brightness meter there, too, has no affect on the actual brightness.
I have searched through a few threads that see that it is a very very common issue and it can be fixed for most people.
Problem is that I am an very new to the Ubuntu universe and I will need a bit more direction to resolve this issue. I know how to pull up the Terminal. But that's about it.
If anyone could please help me with this issue I will be really grateful. I really want to learn more about this operating system.
Thanks in advance.
