Hi there im new to the forums but a log time user of ubuntu. So i recently got given a Imac g4 from work. It does work ( had tiger on it and 'ive run system diagnostics on it).

So i get it home and get ready to install ubuntu (10.10, power pc of course!). so i try ubuntu 10.10 alternate install and it completes and i end up booting to a red screen and stalls. So i figured ill try 10.04 alterante power pc... Same thing i even tryed the install-powerpc command, same thing...

So out of sheer desperation i tryed 9.04 and it boots and runs fine. The upgrade through check for updates doesnt seem to work either...

I want ubuntu 10.10 as thats what all my other computers are running (about 6 other systems) and im a stickler for all having the same os.

Ive tried searching forums, google. etc and havent found any fixes. So if someone would be kind enough to help me resolve this i would be very thankful!

Open source ftw!

You might want to try in a terminal:



wget http://mac.linux.be/files/xorg/imac8.txt
sudo mv imac8.txt /etc/X11/xorg.conf

reboot.
Tell me if it works. If it does not work, paste me the output of

cat /var/log/Xorg.0.log

sorry to sound like a total noob here but its running 9.10 are you saying to do that n terminal then attempt the upgrade? Or to try a fresh 10.10 install and somehow do it?

tardis2424,
I have the same iMac G4 :) I somehow managed to get 10.04 installed from a live CD.

Are you clearing PRAM? (hold down Command, Option, P and R keys all at once as soon as you turn the power on). I let it chime at least three times before I try booting off a cd or anything.

Wishing you good luck - let us know how it goes.

With all versions of Linux you will have to set X manually. There is no escape.

I wasnt questioning that i was asking how to do it....

so heres where im at i cleared the pram ,i installed 10.10 alternate off of the cd (had to do alternate cause my unit only has a cd drive and power pcs dont boot off of usb).

it looked ok rebooted and i get the following error - ( 16. 964991) fb: conflicting fb hw usage noveaufb vs 0Ffb NVDA,MVMac- removing generic driver and a prompt at which it crashes....

please help a noob fix this i want this system usable!

I told you already in post #4.

Boot into Linux from yaboot with a 1 added, so probably

Linux 1

then do as in #4.
Then CTRL-D to resume booting

So the Linux 1 command leads to the same error and crash, no terminal cant type a thing....

Any other ideas?

Tardis2424,
Try holding down the "shift" key when you boot Linux 1,etc.

If that does not work, when you tried 9.04, was it an install or a live cd? Since you posted that version worked, grab the live cd version of 9.04 and boot it so you have a chance to fix the driver on your installed version.

Got a similar issue. But I dont get a ubuntu login sound, just a red screen of death after the yaboot, boot: prompt - so I dont think Im yet up to the stage where i need to fix xorg stuff. Am going to try ubuntu 9.04, with the alternate install rather than the live one. Or maybe I will download both, no live ubuntu has worked for me as yet, you said 9.04 worked as a live CD/DVD?

Fixes for screen problems can be found on this thread: http://ubuntuforums.org/showthread.php?t=1798792

For example, at the second yaboot prompt type "Linux video=ofonly nosplash"
