I have an Acer Aspire One 722 netbook with a C60 CPU and a ATI Radeon™ HD 6250 GPU. I am trying to decrease the power usage and have tried Jupiter and Powertop, but the lowest power usage has been by installing the proprietary driver. I installed the most recent driver from the amd website (amd-driver-installer-12-3-x86.x86_64.run) and the power consumption is very, but now the system won't resume from suspend.
This site says suspend works (I tried editing the /etc/X11/xorg.conf mentioned, but it didn't fix the issue) http://wiki.cchtml.com/index.php/Ubuntu_Natty_Installation_Guide#Suspend.2FHibernation
but this site says it doesn't https://help.ubuntu.com/community/AspireOne522#Suspend_and_hibernate
I am running 11.04 with kernel 3.0.0-12
