Whichever you choose to use, make sure it is the '+mac' version, e.g. 'kubuntu-12.04-desktop-amd64+mac.iso' or its Ubuntu equivalent (which explains why your earlier posted first ISO try did not work), and remember to use 'noapic nomodeset' as kernel parameters for the install.
    Thanks for posting this info.

    Now, I know that we have to use '+mac'.iso's inorder to be able to boot properly with macbookpro.

    I will try downloading this '+mac".iso and create usb installer.

    Thanks again.

    Edit:

    However, if you read the ubuntu download for iso (below). You most likely to download the PC iso for intel chip set for Macbookpro.

    Update:

    It seems that even "+mac".iso got the same unuseable display (see the entry at the very end of this post).

    http://apple.stackexchange.com/quest...na-macbook-pro

    Update 2:

    I managed to install 12.10 night build but updating to 3.6-rc7 and 3.6 night build, AMD (i.e. mac) version. However, the keyboard is not working with this updates. This is ubuntu install is using external usb 3.0 hard drive. The default kernel (3.5) works in this install (usb external drive) but no nvidia and apple gmux yet. I refer linut mint 13 (classical UI) than Unity.

    This is the problem with 3.6 kernels (i.e. HDIO get identity failed for dev/sdb invalid argument) installing in usb hard drive.

    /dev/sdb to /dev/sdc problem

    http://serverfault.com/questions/348...n-when-copying

    http://ask.fedoraproject.org/questio...-after-suspend

    Update 3.

    Linux kernel 3.6-rc7

    I tried updating 12.10 nightly build (22 September) and linux mint 13 with 3.6-rc7 kernel. I got the same problem attributed to Apple Bluetooth. It hangs and the power to usb drive stop as well. It is not booting.

    Linux kernel 3.6 is released today by Linux. It has 2 bluetooth fixes and 1 usb fix as well. Hopeful these fixes solve this problem mentioned above.

    Will try 3.6 ubuntu kernel when available.

    Anybody managed to boot 3.6-rc7 ubuntu kernel with their Macbookpro? And what is the CPU?

    Update 4.

    Turning bluetooth ON in Mac OS X (with Intel graphic (integrate only)) before rebooting with usb 3.0 hard drive installation (updated to 3.6-rc7) boots to get the log screen. However, keyboard is not working (i.e. you can use the keyboard to login in). In 3.5 the keyboard is working.

    Linux 3.6 kernel ubuntu is not avaiable. Time to install and test
    http://kernel.ubuntu.com/~kernel-ppa.../v3.6-quantal/

    The keyboard still the problem in 3.6 kernel. Keyboard backlit is ON but the keyboard is unusable.

    3.5 kernel is still the best for retina. It needs just to be patched to get it fully working with ubuntu.

    Waiting for 3.6 kernel ubuntu ISO.

    Re: ubuntu on new retina macbook : any experience ?

    I ran into a stability issue with Oracle's closed version of VirtualBox 4.2.

    Since the install, there is a distinct interference between my display (i915 only) and the wireless. Wireless connections are constantly dropped, or peer-reset, while the screen goes haywire, presenting distortions akin to video-tearing. The higher the up-/download rate, the worse the distortions.

    Installing Win 7 (32 bit) or XP as guests works, but re-sizing the guest-window breaks the Guest installation (black guest window, appears irrecoverable).

    Switching over to discreet-card-only + NVidia-current resolves the display issue, and allows the guest-window to be freely re-sized, but the wireless remains somewhat unstable. Reverting to VirtualBox 4.1 does not appear to help either.

    After a couple kernel panics on booting the host, I finally purged VirtualBox. The funny bit is that, since the first VirtualBox install, KDE reports a crashed program on start-up, with the illustrious declaration that I'm "not allowed" to receive further information about it --- go figure.

    Has anyone else had better luck getting VirtualBox to work on an rMBP.

    PS: It seems the crash is caused by bluedevil, which ran just fine before the VirtualBox install.

    This bug might not be fixed in 3.6.0 kernel earlier release but hopefully fixed in the new ones.

    Ubuntu 12.10 with 3.5.3 kernel. Is good for retina?

    http://www.kernel.org/pub/linux/kern...hangeLog-3.5.3

    Does this release boots well with MacbookPro retina?

    Edit.

    It seems that it is 3.5.4 kernel, not 3.5.3.

    I hope nvidia card works by default.

    Yep, it works great, and has quite a bit better support than 12.04 did.

    I'm still having trouble with the brightness control and the wifi is flaky sometimes, but overall it's way better.

    I just wrote a blog post about my experience installing 12.10. Hope it's helpful to you!

    Could you elaborate more about it? For example, nvidia card, resolution, etc.

    Sure, the nvidia drivers work as long as you switch to EFI booting, and native resolution worked fine too.

    Brightness and wifi were the only issues I ran into. Oh, and compiz crashed now and then.

    Re: ubuntu on new retina macbook : any experience ?

    I used to have some problems with the brightness controls, but found a simple enough way to overcome them (at least in KDE).

    The main problem lay in the system using the wrong interface to adjust the backlight brightness. Additionally, when using the NVidia proprietary drivers, apple-gmux.c (quite properly) unregisters all backlight interfaces other than the gmux interface, except that the system does not appropriately re-adjusts the interface it uses.

    Keeping apple-gmux.c from un-registering the acpi_videoX interfaces can be done by simply commenting out the according instructions. The patch below should apply cleanly to 3.5.x and 3.6.x kernels. (Otherwise just do it by hand.)

    Code:
    --- a/drivers/platform/x86/apple-gmux.c	2012-09-30 19:47:46.000000000 -0400
    +++ b/drivers/platform/x86/apple-gmux.c	2012-10-11 09:02:32.100752458 -0400
    @@ -511,8 +511,8 @@
     	 * Disable the other backlight choices.
     	 */
     	acpi_video_dmi_promote_vendor();
    -	acpi_video_unregister();
    -	apple_bl_unregister();
    +	//acpi_video_unregister();
    +	//apple_bl_unregister();
     
     	gmux_data->power_state = VGA_SWITCHEROO_ON;
    Once recompiled and running, /sys/class/backlight will contain the two additional interfaces apci_video0 and acpi_video1. On the other hand, if your using the i915, then the system uses the intel_backlight interface.

    Either way, synchronizing changes from the DE used interface to the gmux one, can now be done using inotify via a simple script, which works equally well, regardless of which drivers your using.

    Code:
    #!/bin/bash
    # 
    # references: 2012/10/11, KDE 4.8.5, Kernel 3.6.0, NVidia drivers 304.51
    #   requires: inotify-tools 
    #             patched apple-gmux.c for use with NVidia drivers
    # 
    # On a MacbookPro 10,1 KDE has trouble adjusting the screen backlight, 
    # automatically (timed dimming/power-state changes) as well as manually.
    # 
    # This results from a bug in KDE Powermanagement Tools, 
    # (https://bugs.kde.org/show_bug.cgi?id=296403) which apparently 
    # do not properly update which backlight interface to use.
    # 
    # This script synchronises backlight adjustments/changes to 
    # /sys/class/backlight/gmux_backlight.
    #
    # NB: If i915 is used, no alterations are necessary.
    #     If the proprietary NVidia drivers are to be used, apple-gmux.c needs
    #     to be patched to stop it from disabling the acpi_videoX interfaces.
    #     
    
    # KDE adjusts either via intel_backlight or acpi_videoX,
    # depending on which GPU and which driver is used
    if [ -f /sys/class/backlight/intel_backlight/max_brightness ]; then
        # for i915 use intel_backlight
        ACPI_DIR=/sys/class/backlight/intel_backlight
    fi
    if [ -f /sys/class/backlight/acpi_video1/max_brightness ]; then
        # if NVidia drivers are used, and apple-gmux.c has been patched, use 
        # acpi_video0 or acpi_video1 ... whichever works
        ACPI_DIR=/sys/class/backlight/acpi_video1
    fi
    
    # gmux uses a different range of backlight adjustment, so we scale ...
    ACPI_MAX_BRIGHTNESS=`cat ${ACPI_DIR}/max_brightness`
    GMUX_MAX_BRIGHTNESS=`cat /sys/class/backlight/gmux_backlight/max_brightness`
    MULTIPLIER=$(echo "scale=5;${GMUX_MAX_BRIGHTNESS}/(${ACPI_MAX_BRIGHTNESS}+1)"|bc)
    
    # trigger minimum/maximum screen illumination if we're close enough,
    # i.e. no 2% or 99% brightness ... it's just cleaner this way
    MIN_BACKLIGHT_FACTOR=.05
    FULL_BACKLIGHT_FACTOR=.95
    GMUX_TRIGGER_MIN=$(echo "(${MIN_BACKLIGHT_FACTOR}*${GMUX_MAX_BRIGHTNESS})/1"|bc)
    ACPI_TRIGGER_FULL=$(echo "(${FULL_BACKLIGHT_FACTOR}*${ACPI_MAX_BRIGHTNESS})/1"|bc)
    
    # now sync all changes to gmux in scale 
    # with cut-offs specified by min/full triggers
    while inotifywait -e modify ${ACPI_DIR}/brightness >/dev/null 2>&1; do
        ACPI_BRIGHTNESS=`cat ${ACPI_DIR}/brightness`
        GMUX_BRIGHTNESS=$(echo "(${MULTIPLIER}*${ACPI_BRIGHTNESS})/1"|bc)
        if [ ${ACPI_BRIGHTNESS} -ge ${ACPI_TRIGGER_FULL} ]; then
    	GMUX_BRIGHTNESS=$GMUX_MAX_BRIGHTNESS
        fi
        if [ ${GMUX_BRIGHTNESS} -le ${GMUX_TRIGGER_MIN} ]; then
            GMUX_BRIGHTNESS=0
        fi
        echo ${GMUX_BRIGHTNESS} > /sys/class/backlight/gmux_backlight/brightness
    done
    Just start the script from /etc/rc.local, and backlight adjustment should work just fine, with one exception. On my system (12.04) the brightness will not adjust under NVidia drivers after a boot, but works just peachy after a suspend.

    Looks like Linux 3.7 has support for the microphone now:
