I am going through the kernel team's wiki pages on suspend bugs. My
search on launchpad didn't find any duplicates yet but I'm still
looking. I found some instructions and followed them to get the
following result:

When I try to suspend I get a black screen with the backlight on. I am
using the proprietary AMD drivers at the moment. I enabled the
"ATI/AMD proprietary FGLRX graphics driver" via "Additional Drivers"
on Ubuntu 12.04.
