Macbook Pro 8,2 (radeon Hybrid graphics and Ubuntu 16.04)

[Stephen Partington]

I have been working at this for the better part of the day.

i can get booted into installation by modifying grub.conf on the
installation USB i am using. (see
https://ubuntuforums.org/archive/index.php/t-2157775.html) this allows me
to install. And side-stepping the lack of wifi support was easy with a
Cisco WirelessN usb dongle, so i now have updated kernel and the like as
well as the BCM wireless chipset.

the issue i am still running into is a graceful way to get the hybrid
graphics running.

the system is 100% linux Ubuntu 16.04 64 bit. but i have no screen because
of the weird hybrid graphics issues. the challenge is i cannot dig up and
modify a grub.conf in this scenario because the system is set up to boot
via UEFI and it does this well.

How can i get a command line long enough to configure graphics? I would
assume passing args to UEFI is key, but what am i modifying?
