Abstract: Exemplary embodiments of methods, apparatuses, and systems for seamlessly migrating a user visible display stream sent to a display device from one rendered display stream to another rendered display stream are described. For one embodiment, mirror video display streams are received from both a first graphics processing unit (GPU) and a second GPU, and the video display stream sent to a display device is switched from the video display stream from the first GPU to the video display stream from the second GPU, wherein the switching occurs during a blanking interval for the first GPU that overlaps with a blanking interval for the second GPU.

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.
