Abstract
Remote desktop servers include a display encoder that maintains a secondary framebuffer that contains display data to be encoded and transmitted to a remote client display and a list of display primitives effectuating updated display data in the secondary framebuffer. The display encoder submits requests to receive the list of drawing primitives to a video adapter driver that receives and tracks drawing primitives that, when executed, update a primary framebuffer.
