I now have newer informations. I've been able to boot on Ubuntu 10.10 64 bits with Grub-EFI and Nouveau involved but it needs a 2.6.38.2 (at least, it's the one I have tested). I couldn't make it work with the 2.6.35.
I now have 2 cores. If you want to stick with the 2.6.35, I've been able to have the 2 cores but with the Nvidia Binary. And with this latter, to change the brightness is a pain. To sum up : refit + grub-pc + nouveau => works if maxcpus=1 as a grub option. refit + grub-efi + nouveau => doesn't work. Can't boot. refit + grub-efi + nvidia binary => works and you have 2 cores, 3D and compiz effect but it's a real pain to change the brightness plus it's a blob. refit + grub-efi + nouveau WITH a kernel at least 2.6.38 => works like a charm : 2 cores, 2D and you can change easily the brightness I hope this can help some of you. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/341230 Title: Booting linux crashes on 2009 White Macbook (hardware version ID "MacBook5,2") unless you use acpi=off or maxcpus=1 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
