The disclosed embodiments provide a system that configures a computer system to switch between graphics-processing units (GPUs). In one embodiment, the system drives a display using a first graphics-processing unit (GPU) in the computer system. Next, the system detects one or more events associated with one or more dependencies on a second GPU in the computer system. Finally, in response to the event, the system prepares to switch from the first GPU to the second GPU as a signal source for driving the display.
