Debian on MacBook Pro Retina 15″

This is a fast&furious how-to about installing Debian on a MacBook Pro Retina 15″ bought on January, 2014¹.
Please note that this how-to may become outdated: last update happened on 16 April, 2014.
Please note that this how-to involves dangerous operations: if you choose to follow this how-to your car may burn, your cat may rape your sister and you may buy a windows phone… no warranty!

I choose to install Debian Jessie 8.0 because:

  • it offers better support to the MBP Retina recent hardware
  • it isn’t actually the stable release but it is pretty stable
  • Jessie will be freezed on November 5 (“Remember, remember, the fifth of November!”) and will become the next stable release in about a year (May 2015)

Installing Debian on MacBook Pro Retina:

  1. download the Debian Jessie testing image (http://cdimage.debian.org/cdimage/weekly-builds/amd64/iso-dvd/) and create a bootable USB (dd if=debian-testing-amd64-DVD-1.iso of=/dev/sdX)
  2. boot your macbook pro holding down command+R
  3. use the disk utility, select the disk on the left panel (for example “251GB APPLE SSD”)
  4. on the partition scheme resize the “Macintosh HD” partition, drag the bottom right edge of the partition scheme up unless you have enought space for Debian (I’ve reserved only 50 GB to MacOSX because I really don’t use it), apply
  5. insert the Debian USB, reboot and hold down the options key (aka alt), remember to connect the LAN adapter before boot to Debian installer (hotplug wont work and wifi needs a non-free firmware), use tg3 as kernel module for ethernet adapter if requested
  6. select the EFI Boot relative to your Debian USB key and continue with the Debian installer (please note that I’ve selected XFCE on advanced options as Desktop Environment)
  7. when the installer arrives at the partitioning step select to proceed manually
  8. you can create the common partitions (boot, swap, root) but I suggest to setup an encrypted system²
  9. complete the install and reboot, you can’t boot Debian at this point, boot MacOS and go further…
  10. download the rEFInd USB bootable version (http://www.rodsbooks.com/refind/) and create a bootable USB
  11. insert the rEFInd USB, reboot and hold down the options key (aka alt)
  12. select the EFI Boot relative to your rEFInd USB key, rEFInd should permit to you to boot your Debian
  13. if you can boot your Debian by the rEFInd USB key just return to MacOS and install rEFInd permanently (it’s easy and a good tutorial is available on its website)

Complete the installation:

  1. update your apt sources.list to include the non-free packages
  2. install additional packages³: apt-get install firmware-linux-nonfree broadcom-sta-dkms
  3. reboot to use wifi and lan adapter
  4. to avoid random controller freeze you need to set a particular kernel boot option, edit /etc/default/grub and add the option libata.force=noncq (es. GRUB_CMDLINE_LINUX_DEFAULT=”quiet libata.force=noncq”) then reboot your system

Please note that the Intel video card works flawlessly, the Retina display is simply awasome but… but you need to adapt your desktop environment to use it on an high (very high) resolution (2880×1800), stay tuned, I will post about XFCE optimization for high DPI display as soon as I can! actually after some time spent to try to adapt XFCE on high resolution I’ve choose anyway to reduce the resolution to 1920×1200 mainly because most of the websites are not ready for high resolutions (low res design). This is not an XFCE fault, XFCE works well with high resolution4.

Please note that if you make use of kvm virtual machines you can be really disappointed about poor performance (install system base of Debian may take hours): don’t worry, you have to use the ext4 mount options nobarrier or barrier=0. If your vm is already installed simply update its /etc/fstab configuration. It’s a little more difficult to apply barrier=0 during installation:

  1. start Debian installer on the virtual machine and go further
  2. when the filesystem is ready (aka when the installation of base system starts) use CTRL+ALT+2 combo to move on the kvm console
  3. type sendkey ctrl-alt-f2 to move on another terminal of the vm
  4. use CTRL+ALT+F1 to comeback on the vm and press enter to start activate the command line
  5. execute the command mount -o remount,barrier=0 /target to disable the ext4 barrier feature
  6. use CTRL+ALT+F2 combo to return on the kvm console
  7. type sendkey ctrl-alt-f1 to return on the usual installation wizard of the vm
  8. use CTRL+ALT+F1 to comeback on the vm and complete the installation

If you want to use an external monitor no problem, just apply your custom setup with the xrandr command, for example:
xrandr --output DP1 --mode 1920x1080 --output eDP1 --mode 1920x1200 --below DP1
Run xrandr without arguments to list your screen(s), their names and their available modes.

Happy hacking!

²create an encrypted system

  1. create a small ext4 boot partition (1G)
  2. create an encrypted partition in the remaining space
  3. create an LVM group in the encrypted partition
  4. create two logical LVM partitions: the swap partition (double the size of your RAM), the root ext4 partition

³firmware package includes tg3 and broadcom package build the wl module needed for the wifi card

4you need to properly set the XFCE dpi option and you need to rebuild the composer theme because it uses raw images to compose its windows (download source package xfwm4-themes, edit the theme makefile and do some imagemagick tricks, feel free to ask if you are interested)
