i have the exact same problem as Polaris, except my graphics driver is a RADEON X300 SE 128MB Hypermemory. It also says that there is a secondary one.

Is this a new problem? Were things working OK previously? Any new hardware and or software?

What is your exact problem?

Hyperthreaded GPU's are normally listed with a secondary in the same way that hyperthreaded CPU's are listed twice.
