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".
