No, I was wrong. It happens only with the latest i386 ISO of Feisty. Edgy and Herd 2 do not even start X.
I startet the normal live CD without any changes in configuration. You see the lspci -vv, /etc/X11/xorg.conf and /var/log/Xorg.0.log here: http://www.netaction.de/bin/ubuntu/details/ -- Feisty Herd 1 live cd doesn't recognize iMac resolution https://launchpad.net/bugs/76318 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
