Abstract
A method provides a graphical interface for a computer system and includes receiving window information from each domain of multiple domains in which applications execute. Based on the received window information, the method builds the graphical interface on a graphics device of the computer system from graphics data provided from the multiple domains to the graphics device. The graphics device includes a GPU and graphics memory having multiple graphics memory portions, where each domain is dedicated a respective different graphics memory portion and is given write access thereto. The building issues commands to the graphics device that instruct the GPU to composition together graphics data from graphics memory portion(s) to thereby composition together graphics data from each of two of more domains of the multiple domains. The method also includes issuing commands to the graphics device to output the graphical interface to a set of one or more display devices.
