Bug Description

When Grub is installed on an Apple laptop, and the install is in single-boot mode, with the screen hidden by default, no key on the Apple keyboard will make the hidden grub screen visible. If Ubuntu blackscreens at first boot after install, there is no way to bring up the grub menu and edit the boot parameters to "nomodeset" in order to get to a visible desktop.
This is an Apple-specific problem and is not present on a PC.
