I just tried Xubuntu live cd in case there was an out of memory situation and booted it with the same kernel and the video=ofonly parameter. Both 'startx' and 'startxfce' yields the same SIGSEGV fault in the Rage 128 driver related to the mmio call.
The system doesn't die however so I now got a prompt to play around with and I guess 128 Mb actually is too little for Ubuntu Desktop after all. Maybe a graceful detection of this would be nice instead of a system lockup. For the iMac I continue to use Xubuntu but I will try the Ubuntu-server live cd as well. -- [R128] Dapper ppc install cd SIGSEGV initializing X on iMac https://launchpad.net/bugs/63072 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
