I have the same issue as well (macbook pro 5,2, 17") I think that the 2nd issue (after disabling nouveau and continue to boot) might be a FOSS wireless driver for the mac's broadcom NIC, which fails to load. These issues are similar for both i386 and amd64 variants.
My workaround was, as already described, to install Karmic and upgrade from there, installing the restricted drivers for the nvidia and broadcom cards; to make it boot I had to install grub2 into the partition my Lucid was on, in my case /dev/sda4. And I agree with "cv" - this issue should be raised to 'high' or 'critical' as this is a complete show-stopper for those macbook users curious to try Lucid. And, considering how *nice* Lucid really is, that would be a real shame. :) -- MacBook Pro 5,2 fails to boot into 10.04 beta1 desktop https://bugs.launchpad.net/bugs/546393 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
