I first tried a Lubuntu 16.04 install image but after installing, I couldn’t get it to boot. yaboot would run and give me a menu to choose linux but when I selected it, it just returned to the mac boot menu. I think they got the open firmware boot command wrong but I can’t figure out what they are calling since it goes by so fast.

Try booting with SMP disabled. You can do that at the boot loader prompt and if
that works, you can add an entry to /boot/loader.conf.

This get 12 or head working for me (with one CPU) on two dual CPU G5s.
