Same problem, MacBook Pro 8,2. I tried noacpi, and it makes no difference. I also tried adding the outb commands to Grub in order to switch from the ATI discrete card to the Intel integrated one. This resulted in the screen turning on with some garbage (12.04) or what appears to be a dark maroon background (12.10 Beta1).
I would really like to get the EFI installation. I currently have 12.04 running successfully on this machine, but battery life is abysmal (1.5 hours compared with 7 hours on Mac OSX) and it heats up noticeably. I saw several reports that this is mainly due to the use of the Radeon graphics card, for which I have no use. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1001091 Title: "EFI Boot" from livecd fails on Macbook Pro To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1001091/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
