Abstract: The disclosed embodiments provide a system that facilitates seamlessly switching between graphics-processing units (GPUs) to drive a display. In one embodiment, the system receives a request to switch from using a first GPU to using a second GPU to drive the display. In response to this request, the system uses a kernel thread which operates in the background to configure the second GPU to prepare the second GPU to drive the display. While the kernel thread is configuring the second GPU, the system continues to drive the display with the first GPU and a user thread continues to execute a window manager which performs operations associated with servicing user requests. When configuration of the second GPU is complete, the system switches the signal source for the display from the first GPU to the second GPU.

Abstract: An operating system creates one or more virtual display interfaces for communication of display data and user input events between the application layer and one or more virtual display devices. The one or more virtual display devices are not physically connected to the computing system managed by the operating system. One or more applications are executed in an application layer. At least one of the one or more applications communicates display data to and receives user input events from at least one of the one or more display devices using at least one of the display interfaces. At least one other of the one or more applications communicates display data to and receives user input events from at least one of the one or more virtual display devices using at least one of the one or more virtual display interfaces.
