Hello all, Just need to know exactly how the function vga_setdisplaystart() operates. I can think of two possibilities: a) The page switch takes affect during the NEXT vertical blank. b) The page switch happens immediatley. If it works like case "a" then I would do something like this: vga_setdisplaystart(); // page flip vga_waitretrace(); // only takes affect now however if its more like case "b" then I`d do this; vga_waitretrace(); // wait for the blank vga_setdisplaystart(); // switch pages Hope that makes sense, James ------------------------------------------------------------------ Unsubscribe: To: listbot@svgalib.org Body: unsubscribe linux-svgalib
