I'm fairly new to Ubuntu and Unix based systems as a whole. So far, my only concern is that my graphics cards are not waking from sleep (hibernate?) mode. When I move my mouse or hit a key on my keyboard while it is in sleep, I hear my CPU and case fans turning on. However, I do not hear my GPUs. I have two HD Radeon 6870s with AMD's proprietary driver installed from their website. I am also running Ubuntu alongside Windows using Wubi.
Any help would be much appreciated.
