Lucid will not boot after install (iMac G4)

[cheeseburgerpizza]

I installed Lucid PPC on a G4 iMac (lamp-style, 800 mhz) using the netinstall mini cd. The install environment booted and installed a base system without any problems. However, when trying to boot into the installed system, I get about a second of text after the yaboot screen, then darkness, then a full screen of bright red. Note that X is not installed, so the red screen is not an xorg problem.

I've tried booting with "Linux nosplash video=ofonly", and "Linux single" but the problem occurs in both cases. I can use rescue mode on the cd and chroot into my system on the hard drive, but I'm not sure what steps to take from that point. It does seem to be a functional system when I'm chrooted, I can use apt etc.

I don't want to give up on this installation and install karmic yet, so any ideas about how to fix this broken install would be greatly appreciated.

It still seems like an X issue. Don't know exactly what Lucid does, but I would try to use a working xorg.conf file.

I do believe this fellow just said he hasn't installed x yet. If he is using and ubuntu mini image, it doesn't install by default. He can make an xorg.conf, but there is no xserver there to read it yet.

OP:
Do you know what model of video card is in your mac? can you look it up on everymac.com for us? Maybe we can pass on some framebuffer settings through yaboot

[sha.goyjo]

Can you try passing

video=vesafb

To the kernel at boot time?

Let us know if that helps at all.

I also have a G4

The problem happens at install as well (using a DVD). It won't even go to the splash screen once I typed in "live", "live video=ofonly, "live-powerpc", and "live video=vesafb"

You might want to have a look at turning off KMS
https://wiki.ubuntu.com/X/KernelModeSetting

I tried the KMS thing and no luck.
I even tried upgrading from 9.10.

My boot only goes as far as the boot loader for the powerpc. After that it is a red screen right after it starts loading the kernel and just before the splash screen.

Install Debian Lenny Mint LXDE, Conal can agree on that. It will run fine on an iLamp.

Thank you! I will test this out. I just really like Ubuntu, because I notice amazing improvements in every upgrade.

I have tried it and it seems like it doesn't want to boot.

[Beeblejj]

I have tried it and it doesn't seem to work. I've gone back but I have another problem. Live login won't work. Reburned disc and formatted all partitions except APPLE. Nothing.

Oct 4. To date I have tried 8.10, 9.10, 10.04. Problems all round.
