as best i know such an event doesn't exist anywhere. since x is the one who is
in charge of the gfx chip interface - thus also the vga/dvi/whatever outputs -
this is best added as an X event. some client process (wm, or whatever) can
listen for it and when a screen is plugged or unplugged do some appropriate
action defined by the user/config
