So I just successfully installed Ubuntu 12.04 LTS on my retired PowerMac G5. Everything is working great, but I would like to run this computer headless and use either SSH or VNC to control it.
It appears that Ubuntu or Yaboot refuses to boot without a monitor being connected to the graphics card.
I found: How to remove the graphical user interface? but that only applies to GRUB, which I assume cannot be used on a PowerPC computer.
I'm assuming I need to change something in yaboot.conf, but I can't find an clear advice.
