This is dependent on the OS you're booting - it will need its own
support for the graphics device that you're using on your machine there.

I'm assuming that this is an OpenPower machine, which has an ast
graphics device. Ubuntu 14.04.3 should have support for this device by
default, and, I believe, later versions too. Are you booting into the
Ubuntu installer, or an already-installed Ubuntu?

Also, this question might be more appropriate for the OPAL firmware
emailing list, which I have CCed.
