brightness

I have an otherwise fully-functioning install of Ubuntu 12.04 on my HPdv7t laptop.

When I press the 'brightness buttons' on the keyboard the associated images appear on my screen to say I am increasing/decreasing the screen brightness. When I go into "System Settings" I can move the 'brightness slider bar' up and down.

But none of that changes the fact that my screen is stuck on the highest brightness setting.

ANY clues on how to fix this would be greatly appreciated. This giant 17-inch monitor is blinding, and this is making it hard to code for any length of time.

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.

Why does my laptop resume immediately after suspend?

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I seem to be having some problem with suspend mode. Every time I try to suspend my laptop, it just locks the screen. Or maybe it successfully suspends just to resume only an instant after. What could cause such a behaviour? I'm running 32-bit Ubuntu 12.04 with the 3.2.0-25 kernel on a HP dv5-1178er… >>> More
