I'm getting freezes on my Ubuntu 10:10 Linux at random times, I get a screen with vertical colored lines and I have to turn it off with the power switch. Then Reboot,  I've done some research and the s3g unichrome pro IGP keeps on coming up. saying that the drivers are the problem. So I need drivers for s5g video on my mother board. I'm completely new to Ubuntu so keep it simple please.
Thank you
Jon
