I found an old G4 PowerMac (Silver 2002 AFAICT, 933MHz CPU with 256MB PC133 RAM) the other day and decided to use it as a server. I've done all this many times before on PC hardware, though never on Mac hardware. I managed to install Ubuntu Server 10.04, wiping the existing OSX install. It all installed, rebooted, after the yaboot prompts it flashed black text on white background, then the monitor went dead: I could not access the console. But I could SSH into it over the network, so I installed and configured the services I wanted.
However this morning I had to move the machine (only a few metres, so using the same cables and ports), so I SSH'd in and
sudo halt, unplugged, replugged and now I can't even get SSH access (Connection refused; ping works). The monitor was doing the same thing as previously. The plan was to make it headless later, but it still had the monitor plugged in. (Removing the video card and it doesn't boot at all)
I've tried a few things at the boot: prompt:
Linux video=ofonly and
Linux video=nvidiafb but there's no difference. Other Google searches are fruitless. The "Apple Hardware Test" image found no problems. I'm not sure if the video problem is stopping sshd from starting, or something else.
Other ideas? Thanks
