Well looking at the actual figures my guess is you started CPU mining instead of GPU mining ... or cgminer couldn't detect the GPUs

The command "./cgminer -n" will tell you if it can see any GPUs

If it can't well there are things like ... is the window manager running on the machine?
Is your DISPLAY correct and does it have access
Does aticonfig see the cards

(... and other such things listed in: ... linux-usb-cgminer)
