Public bug reported: I wanted to test Ubuntu 15.10 from live USB on a MacBook Pro 8,2 with Radeon HD 6770M. Currently, the machine has installed Ubuntu 15.04 with Radeon disabled in grub and works well. I have installed this booting the live USB of Ubuntu 15.04 through a 'nomodeset' command in grub options. I'm looking to do the same to testing live the 15.10, but it seems not work.
If I boot the USB normally, the boot stopped at [6.9] with "i8042: No controller found" issue. If I boot removing "quite splash" from grub, the boot stopped at [7.3] with "fb: switching radeonfmfb from EFI VGA" issue. If I boot removing "quite splash" and adding "nomodeset" in grub, the boot stopped after a couple of minutes on "[ OK ] Started WPA supplicant". ** Affects: ubuntu Importance: Undecided Status: New ** Tags: 15.10 ** Tags added: 15.10 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1497905 Title: Unable to boot live 15.10 on MacBook Pro 8,2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1497905/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
