I am new to Ubuntu, but so far I am loving it.

I was always unable to change my brightness since I installed Ubuntu, but I figured that installing the latest ATI driver for my graphics card would work.

I did, but I still can't change the brightness. The slider goes up and down, but the brightness stays the same (on full).

I have switchable graphics, an ATI Radeon HD 6770M, and an Intel integrated GPU.

Since I am new to Linux, I am not familiar with terminal, so you will have to spell everything out for me, including if you need more information and how to get it.

Thanks.

Will final version of 12.04 use the power management changes found in kernel 3.3

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
