I have Acer 722 netbook with C-60 APU 1GHz and AMD 6290 graphics. I upgraded my 11.04 to 11.10 and there are less functions in power managements, I have no control when my machine sleeps, hibernate, no brightness control, etc. Another problem is that whenever I unplug my machine (at any battery level), it would prompt battery low, machine will hibernate. Is there a way to fix this? Is there a better power managements option?

Most of your problems are a function of the kernel. I would suggest you file a bug report and keep trying new kernels as they become available. –  bodhi.zazen Apr 5 '12 at 19:56
    
I guess they will fix it in the next release of Ubuntu 12.04. –  stacker1412 Apr 9 '12 at 19:01
