    even though that result say there's one core, both cores are actually working or not?
    if not, what should i do to solve this? any solution?
    i want 2 cores.
    with one core, of course, it plays 720p hd video. but it eats 100% cpu usage..
    I think it's a bug in the kernel. I don't remember if there's a solution yet.
    Here's the bug report, you might be able to find some helpful information or a workaround:

    Re: Installation crashes on the new early 2009 White Macbooks

    I have to say that I didn't suceed in installing ubuntu in the withe macbook5,2 (early 2009 model).

    The installation in the partition seems to be ok. I have done rEFIt and acpi=off I followed you manual and ubuntu's forum official webpage.

    A grub problem always appears. After Sync MBR with rEFIt, it freezes in grub loading stage2 during rebooting ubuntu.

    Could someone help me?

    Thanks

    Installation is a nightmare. I wish I had documented the procedure which worked for me but I didn't.

    I think I used this how-to:
    http://wiki.onmac.net/index.php/Trip...t_via_BootCamp

    BTW I think this is offtopic to the current thread so you should start a new thread if you want help with dual booting Ubuntu on a Macbook.

    -sound & microphone works (only 2 speakers..
    -i can shutdown my macbook
    -i cannot reboot
    -i can enter sleep mode... but i can't wakeup

    but i can't use nvidia drivers so no 3d effects and accelerated graphics.


    here how to make things work:
    0.1 you have to use REFIT, or you have to bless grub.efi in [3] - but it's safer refit - download and install it from osx.
    0.2 boot into ubuntu in some way and install all the needed packages to compile theese things
    1a. checkout the last svn version of grub2 and compile it for the x86_64 efi platform - i followed http://grub.enbug.org/TestingOnMacbook and http://grub.enbug.org/TestingOnEFI..... or download the attached file. the config file is for kernel version 2.6.27-11-generic, but you can change it for your kernel versions
    1b. change, if you set it, in xorg.conf from nvidia to fbdev
    Code:
    Section "Device"
        Identifier     "Device0"
        Driver         "fbdev" #"nvidia"
    #    VendorName     "NVIDIA Corporation"
    EndSection
    1c. add the folling line in /etc/modprobe.d/blacklist
    Code:
    blacklist agpgart
    2. copy the compiled-or downloaded grub2_efi to an usbpen and reboot into osx
    3. paste grub2_efi into /efi/
    4. reboot
    5. now you should see another entry in refit: grub2_efi. boot


    1. here there is some code:
    Code:
    mkdir grub2_efi
    svn co svn://svn.savannah.gnu.org/grub/trunk/grub2 grub2
    cd grub2
    ./configure --with-platform=efi --target=i386
    make
    ./grub-mkimage -d . -o grub.efi gpt hfsplus fat ext2 normal chain boot configfile
    sudo cp grub.efi *.mod fs.lst command.lst ../grub2_efi
    create your own grub.cfg file, or take the mine, and put it into grub2_efi:
    Code:
    menuentry "linux-2.6.27-11-generic" {
      # Set the root device for Linux.
      root=(hd0,3)
      # Load the loader. - other options: video=vesafb noefi
      linux /boot/vmlinuz-2.6.27-11-generic root=/dev/sda3 video=efifb agp=off acpi=force
      initrd /boot/initrd.img-2.6.27-11-generic
    }
    
    menuentry "MacOSX" {
      # Search the root device for Mac OS X's loader.
      search --set /usr/standalone/i386/boot.efi
      # Load the loader.
      chainloader /usr/standalone/i386/boot.efi
    }
    
    menuentry "Boot from MBR" {
      appleloader HD
    }
    menuentry "Boot from CD" {
      appleloader CD
    }
    
    # this does not work for me
    menuentry "Boot from USB" {
      appleloader USB
    }
    
    
    #keymapping: remeber these keys when you boot, they can be helpful!!!
    #F1 = ctrl-x
    #F2 = ctrl-a
    #F3 = ctrl-e
    mmm now nvidia drivers works very well for me.. it seems that point 1b and 1c are no more useful. and i can also wake up from sleep!

    Hello,

    Could you please tell us how you did about enable nvidia. I have tried but it did'n work. Could you post your actual grub.cfg et xorg.conf. Do you always blacklist agp?

    Thank you

    EndSection
    grub.cfg is the same i posted in previous posts-except for kernel version

    nvidia works fine with driver version 180 automagically installed by ubuntu Hardware Drivers. I think that with previous versions there were some problems.

    agpgart is no more blacklisted

    Thank you so much. I will try this. By the way, what is your version of Ubuntu 8.10 or 9.04? And one more question, do you recompile grub2 or you use the same version that you've posted here?

    Re: Installation crashes on the new early 2009 White Macbooks

    Is anybody still monitoring this thread? I've stumbled across it as I have the same problem: MacBook5,2, Ubuntu 10.04, grub 1.98, 32 bit version, 64 bit version... I can't seem to get anything to work to get me running with 2 cores and ACPI.

    Any tips?

    I reinstalled from 9.04 to 10.10 (32 bit) - reusing my grub 1.97 (64 bit, loaded into my OSX partition) works with this config:

    Code:
    menuentry "linux latest" {
      root=(hd0,3)
      fakebios
      linux /vmlinuz root=/dev/sda3 video=efifb agp=off acpi=force
      initrd /initrd.img
    }
    I'll try recompiling grub 1.99 per http://grub.enbug.org/TestingOnMacbook and seeing what happens.
