  • sda2: Existing OSX installation
  • sda3: Existing Recovery partition
  • sda4: New /boot partition
  • sda5: New encrypted lvm partition for swap and /

General steps

  1. Unencrypt (if not already) OSX partition to resize and make space for Ubuntu.
  2. Download Ubuntu image: http://www.ubuntu.com/download/desktop/thank-you?country=US&version=16.04&architecture=amd64 and make bootable usb disk.
  3. Boot usb disk and choose ‘Try Ubuntu’ option.
  4. Create an ext2 /boot partition (~512M should be plenty) and an ext4 partition to hold the lvm partition.
  5. Create encrypted luks partition with LV’s for Ubuntu installation / and encrypted swap (at least size of RAM, slightly bigger for hibernation - https://help.ubuntu.com/community/SwapFaq#Example_Scenarios).
  6. Unmount any mounted partitions that will be used in the install.
  7. Run the installer manually specifying the /boot partition in step 4 and the LV’s created for / and swap in step 5, without rebooting or installing a bootloader, and exit installer.
  8. Set up a UEFI bootloader. There are lots of ways to do this. I use systemd-boot, which works fine. Ubuntu mounts the EFI partition (sda1) at /boot/EFI.

Bootloaders

systemd-boot

bootctl install --path=/boot/efi
efibootmgr -c -d /dev/sda1 -p 1 -l EFI/systemd/systemd-bootx64.efi -L "Linux Boot Manager"

Grub EFI

apt install grub-efi
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=grub
grub-mkconfig -o /boot/grub/grub.cfg

Change keyboard fn key behaviour

https://help.ubuntu.com/community/AppleKeyboard

Fn keys by default, fn+ for multimedia keys:

echo 2 | sudo tee /sys/module/hid_apple/parameters/fnmode

Swap cmd and alt keys:

echo 1 | sudo tee /sys/module/hid_apple/parameters/swap_opt_cmd

Clone repo at https://github.com/free5lot/hid-apple-patched and install:

./build.sh
./install.sh

Put options in /etc/modprobe.d/hid_apple.conf

options hid-apple iso_layout=1
options hid_apple fnmode=2
options hid_apple swap_opt_cmd=0
options hid_apple swap_fn_leftctrl=1
options hid_apple ejectcd_as_delete=0
sudo update-initramfs -u -k all
