Abstract
Methods and apparatuses for dynamic virtual frame buffer management. At least one embodiment of the present invention dynamically enables or disables the use of a virtual frame buffer, which is not under control of graphics hardware of a data processing system, without restarting the graphical user interface system (e.g., the window system) of the data processing system. For example, in response to the addition or removing of a frame buffer that is under control of a graphics controller (e.g., due to the activation or deactivation of the graphics controller, or the hot plug-in or hot disconnection of the graphics controller), the virtual frame buffer is disabled or enabled respectively.
