I'm trying to use a mainboard with on-board graphics (ASPEED AST2050) for driving the display together with an HD 6990 solely for computing. The machine runs Windows 7 64-bit Enterprise edition and Catalyst version 11.8. The driver for the on-board graphics is the standard Windows built-in VGA driver.
However, this doesn't work. FindNumDevices reports 0. Catalyst Control Center can't be started. In the Windows device manager, I see all graphics devices listed nicely and "working properly".
Is there a solution?
