Alrighty, long story. I installed Ubuntu Hoary Hedgehog on an iMac G3 a while ago. It had problems with the time (since the battery that keeps the time there is dead), so I re-installed Mac OS 9. It went fine until restart, and the screen didn't work. I've just been using it with an external screen attached to it. Sometimes, if you boot it up, you will get the screen to work but with only one color (every thing's red, blue, or green). These occurences usually are after 50 or so bootups. Also, when the screen is working in one color, it never can display anything graphical, only text. So, I'm just wondering if there's a way to reset the screen by software. Can any of you guys help me? Thanks.
