iMac Resolution Issue

[Mr. Knisely]

I've got a tray loading iMac that I've loaded the PPC verion of Ubuntu 
on. My display settings are very low, under 640x480 but the exact number 
escapes me at the moment.

I've seen others have run into this issue before but I've not found the 
solution for it. Anyone have any suggestions?

Here is my hardware info:
Display:

    code:

0000:00:12.0 VGA compatible controller: ATI Technologies Inc 3D Rage IIC 215IIC [Mach64 GT IIC] (rev 3a)



Dmesg Junk:

    code:

Is there another configuration file that I just don't see?

I hope this is helpful, and I look forward to any suggestions.

Thanks!
