I have searched everywhere on google and various message boards to try to find the solution for my problem. I am trying to pinpoint exactly the solution for the lines that race accross my screen. I get these lines that go across my screen anywhere there is not black space. I have tried to install video drivers, which failed to work, and I am sure there is a tweak to put into X but I can't find what to put where. I have a radeon mobility 7500 with 32MB RAM. This is on an iBook G3 900Mhz if that helps also. Thanks in advance.
