Phill, Again on the iMac G3, this has been a known problem for a while. If folks know its xorg.conf, why can't that simply be fixed? And the problem I'm having now is that Ctrl-option-F1 isn't bringing up a command prompt, so I can't edit the xorg.conf file on the fly with the desktop .iso.
See: https://wiki.ubuntu.com/PowerPCKnownIssues#A8.04_PowerPC_LiveCd_will_not_boot_on_iBookG4 And the instructions below (from that link) don't always, but generally do, get things up an running. Blank screen on iMac G3 Do you get a blank screen after booting? The problem is that xorg.conf is not set up properly for the iMac G3. Follow these steps to fix xorg.conf: After booting is complete: Type: ctrl-option-F1 (should give you a command prompt, may take a couple of tries) Type: sudo nano /etc/X11/xorg.conf (return) In the Monitor section, change "HorizSync" to 58-62 and "VertRefresh" to 75-117. Disable DRI. In the Module section, put a hash mark (#) at the beginning of the line containing "load dri". If you have no Module section, make one like this: Section "Module" Disable "glx" Disable "dri" EndSection Type: ctrl-O (return) to write edited file Type: ctrl-X to exit nano back to command line Type: sudo /etc/init.d/gdm restart (return) to restart Gnome. (In Dapper and Edgy, the restart command is broken. Use sudo killall -HUP gdm instead.)
