This is a particularly nasty bug since basically all flavors of Linux on a large subset of Macbook Pros are unable to boot *out of the box* and require fiddling with kernel boot parameters in grub.cfg to allow the system to limp along until they can install the binary Nvidia drivers.
I have a MacBook Pro 5,1 which has two GPUs: GeForce 9600M GT and GeForce 9400M. I was hoping this thing would be fixed by now and I attempted to boot the latest vivacious vixen (or whatever) nightly build ISO (with linux 3.18 rc5) to check if it was fixed. It's not. Here is a kernel debug log I've collected when the nouveau module is loaded into linux v 3.18 rc5 on my system: http://hastebin.com/qusumotusi.m Hopefully this will help one of you clever devils track down this bug and get a fix merged before the 3.18 merge window closes! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/546393 Title: 10de:0647 [MacBookPro5,2] Fails to boot into 12.04 desktop To manage notifications about this bug go to: https://bugs.launchpad.net/nouveau/+bug/546393/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
