Abstract
One embodiment of the present invention provides a system that switches from a first graphics processor to a second graphics processor to drive a display. During operation, the system receives a request to switch a signal source which drives the display from the first graphics processor to the second graphics processor. In response to the request, the system first configures the second graphics processor so that the second graphics processor is ready to drive the display. Next, the system switches the signal source that drives the display from the first graphics processor to the second graphics processor, thereby causing the second graphics processor to drive the display.
