I appreciate the interest in the problem. The PowerPC FAQ does little to explain the root cause of the problem, but does offer a wealth of information regarding temporary fixes, usually through xorg.conf.

I'm all for getting the problem fixed correctly. At one time the live CD wasn't work on iBook G4's or Powerbook G4's, but that problem has been resolved. (12.04 boots fine on iBook G4, although desktop installer screens are dark).

If there are any logs or screen shots that I can supply to help out, let me know.

Also, is there anything I can do, other than modifying the xorg.conf, to get the live installer to work or the alternate to not boot to a command prompt. I'd just like to test 12.04 on the G3 iMac.

For example, at Yaboot prompt:

live video=aty128fb:1024x768-24@60 video=offb:off  NoUseFBDev

(I'm guessing at the correct syntax based on the PowerPC FAQ and some other notes I have. Not even sure if I can invoke NoUseFBDev at this point.)

I'd still have to write some sort of permanent changes to the new install, wouldn't I?



 

 

Sincerely,
Paul Gorski

Paul and Jim,

If you read the PowerPC FAQ there is a large section on graphics, much of it based around the imac G3.  It explains what is going and why it fails to load.  It explains it much better than I can put in a single post to a message list.

In 11.04 and 11.10 (and at the moment 12.04) the appropraite framebuffer is not built in.  I'm going to file a bug to get the ones used by Apple hardware built back in to the kernel.  This is why the openfirmware framebuffer is loading and causing you problems.

In the past the r128 caused dri lockup.  This is not going to happen in 12.04 because you won't have 3d hardware acceleration.

Please do not include a 5 year plus old xorg.conf file in a recent version on Lubuntu.  The problems are not the same.
