I disabled that function in the bios and it made no difference. I am
beginning to wonder if it's not a problem with X recovering. I can
suspend to disk when after the lid is closed and then opened and
occasionally recover from the suspend. I discovered today that once the
lid is reopened the keyboard is active -- but the display won't 'un-blank'
