jockey crashes at command -l, -c, etc. and gui version crashes at startup

[Andy Williams]

just installed 12.04 lts on a power mac dual g5. It has a gefarce 7800 gt card. parts of the screen look terrible right now, eg: left panel icons are all solid blue?! Anyway, I went to system settings> additional drivers, when i clicked on the icon a window popped up then gone instantly, a few seconds later an error popps up for jockey. It wouldn't show any details as it just sat there with the loading icon. I tried running it from terminal, dis wat i got:

Cannot connect to backend, is it busy?
