After just posting that I couldn’t get it to work, read a post that suggested doing a live-nosplash at the boot prompt and it worked. Seems that there is a problem with the Ubuntu splash screen on the G4 machines. Weird that they haven’t figured it out and corrected it by now.
Got it up and running but the wireless wouldn’t work, however it told me that it needed a proprietary driver and when I hooked the ethernet up it went and got what was needed, installed it, and turned it on. No hassle at all. Unhooked the ethernet and am now running on the wireless card.
Just tried to get to the spell check in Firefox and without a mouse couldn’t get the right click to work so found and plugged in a usb mouse it it too works just fine. Now to clean off some more room on the hard drive and see about installing Ubuntu on it so I don’t have to deal with the Mac DRM any more…
