Bug Description

I just tried to boot Edgy Knot 1 on my iMac 1.9Ghz

  Machine Name: iMac G5
  Machine Model: PowerMac12,1
  CPU Type: PowerPC G5 (3.0)
  Number Of CPUs: 1
  CPU Speed: 1.9 GHz
  L2 Cache (per CPU): 512 KB
  Memory: 1 GB
  Bus Speed: 633 MHz
  Boot ROM Version: 5.2.6f1

I wasn't able to boot this machine under Dapper at all so this is a bit of an improvement. I had to use the suggested boot argument for the video to get past the white screen issue. After that usplash worked fine. Then gdm loads and I just get a black screen for a while. I can hear Gnome loading and then I get distorted graphics on my screen. Very strange.

I own a iMac G5 rev C (PowerMac12,1) like you (but 20", 2,1GHz version). I have the same problem. I reached to configured xorg like described in .

This bug is confirmed.

tas50, Étienne, thanks for the bug report!

Unfortunately we really need more information before we can do anything.

Please follow, and attach the asked files into this bug report.

I'm also marking this bug for the right package (xserver-xorg-video-ati), since it is quite likely a driver problem.

In fact, i think the problem is a sync freq problem. The working xorg.conf use parse-edid result for Monitor section. And ubuntu xorg.conf show a black screen, but i hear the login sound.
