Full shut-down, not + a reboot. + * Test power management by disabling guest screens ("xrandr --output VGA-n + --off") and re-enabling them ("xrandr --output VGA-n --preferred --pos XxY") + where X and Y are the position of the screen before disabling it. + * Test sending video mode hints with screen position information via + VBoxManage.
