this bug post is only about MacBookPro3,1. in ubuntu 15.10 the nouveau driver did not work but nvidia drivers did. now, in ubuntu 16.04, the nvidia drivers also do not work.
just to see why nouveau fails i uninstalled all nvidia packages and purged dependencies. while booting without splash the output in the console stops at the message "fb: switching to nouveaufb from EFI VGA" and the dmesg has some more: fb: switching to nouveaufb from EFI VGA Console: switching to colour dummy device 80x25 nouveau 0000:01:00.0: enabling device (0002 -> 0003) nouveau 0000:01:00.0: NVIDIA G84 (084700a2) nouveau 0000:01:00.0: Invalid ROM contents nouveau 0000:01:00.0: bios: unable to locate usable image nouveau 0000:01:00.0: bios ctor failed, -22 nouveau: probe of 0000:01:00.0 failed with error -22 i never really tried to get nouveau working with 15.10 so i cannot tell whether this is a regression or not. do you want me to file a separate bug report on nouveau on MacBookPro3,1? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1547599 Title: legacy nvidia drivers fail to work with latest kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-304/+bug/1547599/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
