I just installed Lubuntu 12.10 on two PowerMac G4 machines. The maximum resolution on both of them appears to be 1024x768.

Both machines have a ATI Rage 128 PF/Pro AGP 4x TMDS graphics card.

The first machine has never had Linux on it before. The second machine had Ubuntu 12.04 on it before. I don't remember what resolution it had when it had 12.04 on it, but I'm pretty sure it was higher than 1024x768.

I read some previous posts and it sounds like there have been issues with Rage Pro cards and Ubuntu PPC in the past. Should I revert back to 12.04 and see if the resolution is higher? Or are there some settings that I can try to increase it?
