[lubuntu] Can't login after Lubuntu 12.10 PPC install

view story

http://ubuntuforums.org – I am trying to install lubuntu 12.1 PPC using the alt cd on an ibook g4. I've been having a few problems. First, when lubuntu boots it only boots to a black screen, my cursor is visible and brightness functions work but that's it, no login screen ever comes up. I tried logging in after pressing ctrl+alt+f1 but my login didn't work. I reinstalled thinking maybe I just forgot what password I put, and the problem occurred again, this time yaboot wasn't installed, but it won't even boot to a black screen, and when I try to login using ctrl+alt+f1 it just keeps telling me I have an invalid login de (Hardware)
