Ubuntu on MacBook Air 3,2

[OsricTheKnight]

I did a few things differently than described so far.

First off, I bought a USB->Ethernet dongle because I anticipated wireless problems would be annoying during install.

Then I followed more or less the same directions as everyone else until the end of the install process.

Then, before rebooting, I started a new terminal, and ran:

cd /tmp
mkdir mntroot
sudo mount /dev/sda3 mntroot

Note that /dev/sda3 is where I installed "/" for ubuntu.

sudo mount --bind /dev ./mntroot/dev
sudo mount --bind /dev/pts ./mntroot/dev/pts
sudo mount --bind /proc ./mntroot/proc
sudo mount --bind /sys ./mntroot/sys
sudo chroot mntroot

at this point, I was sitting at a root prompt on my SSD "disk", ready to fix the grub install. Then I edited /etc/default/grub and made GRUB_CMDLINE_LINUX="nomodeset reboot=pci". Finally I ran

update-grub

and typed "reboot", hit enter when prompted, and had the system reboot. It's now running; the wireless driver was automatically chosen by the install process for me, and wireless is working without the dongle. The Nvidia driver was the first thing I needed to install after that.

Hope this is helpful to others,

With rEFIt installed, and following the instructions to have the disk recognized during bootup, when I select "linux install cd", I just get a "Non-system disk Press any key to reboot" error. I am not using a Superdrive, but I didn't think that should matter.

If I select "Boot EFI\boot\bootx64.efi from" I get GRUB and the "try Ubuntu without installing" and "Install Ubuntu" menu, but if I select either option, I am left with a black screen and no disk activity.

The disk is a 64bit Meerkat CD-R, which has been used on several other machines. I've tried numerous combinations of actions, and nothing seems to be working.

Any thoughts?
