I'm dual-booting a 15" Macbook Pro 5.1 (with nVidia 9400M and 9600M dual graphics cards) with Mac OS X 10.8 Mountain Lion and Ubuntu 12.04 gives me a blank screen before I get to the desktop. I am using rEFInd as a boot loader (and Ubuntu is loaded in EFI mode.)

When installing from a USB drive I can use the graphical installer by using the nomodeset kernel switch (entered using the GRUB interface.)

However, I can't access the desktop using either the try ubuntu without installing or after installation.

I have tried the acpi=off, nomodeset and outb 0x728 1... methods using GRUB, to no avail.

How can I get the desktop to load? Are there any more hacks I can try? Do I need to install graphics drivers?
